Introduction
Have you ever seen the names Mark Gronowski and Rob Gronkowski and wondered if these two football players are family? You are not alone. Their surnames look almost identical, and both have built notable football careers, making the question surprisingly common among fans.
The short answer is no, Mark Gronowski is not related to Rob Gronkowski. The confusion comes mainly from their similar surnames. Mark’s last name is spelled Gronowski, while Rob’s is Gronkowski, with an extra letter in the middle. Their family backgrounds are also different.
Mark Gronowski has created his own football story. He became a standout quarterback at South Dakota State, won two FCS national championships, and later played for Iowa before entering the NFL with the Miami Dolphins in 2026. Rob Gronkowski, meanwhile, became one of the NFL’s most famous tight ends and part of a remarkable family of professional athletes.
So, why are the two names so easy to confuse? The answer becomes clear when you look at their spelling, family trees, and football careers.
Is Mark Gronkowski Related to Rob Gronkowski?
No. Mark Gronkowski is not related to Rob Gronkowski. The confusion comes from a very similar surname and the fact that both men have made names for themselves in football.
There is also an important spelling detail that can easily fool you. The Iowa quarterback is Mark Gronowski, while the former NFL star is Rob Gronkowski. Mark has an extra letter arrangement that makes his surname look almost identical at first glance.
This question became popular when Mark Gronowski joined the Iowa Hawkeyes after a highly successful career at South Dakota State. His name immediately reminded college football fans of Rob Gronkowski, the legendary tight end who starred for the New England Patriots and Tampa Bay Buccaneers.
So, is Mark Gronkowski related to Rob Gronkowski? The answer is no. Their similar names do not indicate a known family relationship.
The Biggest Clue Is the Spelling
If you compare the two surnames carefully, the difference becomes obvious.
| Person | Correct Name | Position | Known For |
|---|---|---|---|
| Mark Gronowski | Gronowski | Quarterback | South Dakota State and Iowa |
| Rob Gronkowski | Gronkowski | Tight end | New England Patriots and Tampa Bay Buccaneers |
Mark’s surname is Gronowski.
Rob’s surname is Gronkowski.
That single letter difference creates much of the confusion online. Search engines, sports fans, and even casual readers can easily overlook it when scanning a headline or roster.
This is why searches for is Mark Gronkowski related to Rob Gronkowski often lead to explanations about Mark Gronowski instead.
Who Is Mark Gronowski?
Mark Gronowski is an American football quarterback who built an impressive college career before transferring to Iowa.
He played his first major college football years at South Dakota State. During his time with the Jackrabbits, he became one of the most successful quarterbacks in FCS football.
According to Iowa Athletics, Gronowski finished his South Dakota State career with a 49 and 6 record as a starting quarterback. He also helped the program win two national championships.
His numbers were impressive as well.
By the end of his college career, Gronowski had recorded:
- 12,049 career passing yards
- 103 career passing touchdowns
- 2,312 career rushing yards
- 53 career rushing touchdowns
- 58 career wins as a college quarterback
Those statistics show why his name became important in college football independently of any connection to Rob Gronkowski.
In 2025, Gronowski played his final college season at Iowa. He completed 166 of 262 passes for 1,741 yards and 10 passing touchdowns. He also rushed for 545 yards and 16 touchdowns.
Iowa Athletics lists those 16 rushing touchdowns and 545 rushing yards as single season school records for an Iowa quarterback.
Who Is Rob Gronkowski?
Rob Gronkowski is one of the most recognizable tight ends in NFL history.
He entered the NFL in 2010 after playing college football at the University of Arizona. The New England Patriots selected him in the second round of the 2010 NFL Draft.
Gronkowski quickly became one of Tom Brady’s most dangerous offensive targets.
His NFL career included three Super Bowl championships. He also became known for his combination of size, strength, speed, receiving ability, and blocking.
The NFL has described Gronkowski as one of the greatest players to play the tight end position. His career statistics and championship record explain why the surname Gronkowski became so recognizable in American sports.
Rob also comes from a famous athletic family.
That fact adds another layer to the confusion surrounding Mark Gronowski.
Rob Gronkowski Has Four Brothers
Rob Gronkowski grew up with four brothers.
They are:
- Gordie Gronkowski Jr.
- Dan Gronkowski
- Chris Gronkowski
- Glenn Gronkowski
The Gronkowski family developed a strong reputation for athletics.
Dan, Chris, and Glenn all reached the NFL. Gordie Jr. pursued professional baseball instead.
That means the actual Gronkowski football family includes Rob, Dan, Chris, and Glenn.
Mark Gronowski is not one of those brothers.
This is one of the clearest ways to understand the answer to is Mark Gronkowski related to Rob Gronkowski.
Why Do People Think Mark and Rob Are Related?
There are several understandable reasons for the confusion.
1. Their Names Look Almost Identical
Gronowski and Gronkowski are extremely similar surnames. If you read them quickly, you may not notice the missing letter.
2. Both Are Football Players
Mark became a prominent college quarterback. Rob became an NFL superstar.
When two athletes have almost identical names and play the same sport, people naturally wonder whether they come from the same family.
3. Rob Has a Famous Football Family
The Gronkowski family is well known because several brothers played professional football.
That makes it easy to assume that another football player with a similar name could belong to the same family.
4. Mark Became a Major College Football Name
Mark’s success at South Dakota State and Iowa gave his name significant attention.
His move to Iowa brought even more national coverage. Sports outlets such as Sporting News and Pro Football Network specifically addressed the question of whether he was connected to Rob.
Their conclusion was the same. There is no established family relationship between the two athletes.
Mark Gronowski and Rob Gronkowski Have Different Football Stories
Another useful way to separate the two players is to look at their careers.
| Category | Mark Gronowski | Rob Gronkowski |
|---|---|---|
| Sport | American football | American football |
| Position | Quarterback | Tight end |
| College | South Dakota State and Iowa | Arizona |
| Professional NFL Career | No | Yes |
| Major College Success | Two national championships | College standout |
| NFL Super Bowl Titles | None | Three |
| Famous Family | No established connection to Gronkowski family | Four athletic brothers |
Their positions also show how different their football journeys have been.
Mark operated as a quarterback. He was responsible for directing the offense, making reads, throwing passes, and contributing as a runner.
Rob played tight end. His game centered on receiving, blocking, creating mismatches, and using his physical size against defenders.
Their careers overlap only in the broad sense that both played football at a high level.
An Interesting Statistical Comparison
Comparing their statistics can be misleading because they played different positions and different levels of football.
Still, the numbers demonstrate how successful both athletes became.
Mark finished his college career with more than 12,000 passing yards and more than 2,300 rushing yards.
Rob finished his NFL career with 9,286 receiving yards and 92 receiving touchdowns.
Mark’s numbers show the production of an accomplished college quarterback. Rob’s numbers show the impact of an elite NFL tight end.
This distinction matters when you search is Mark Gronkowski related to Rob Gronkowski because similar names do not mean similar careers or shared ancestry.
What Do Sports Experts and Records Show?
The strongest evidence comes from consistent biographical records.
Major sports publications that have examined the question identify Mark as Mark Gronowski, not Mark Gronkowski. Iowa’s official athletics records also use the Gronowski spelling.
Meanwhile, Rob’s official football history consistently identifies him as Rob Gronkowski.
The family records surrounding Rob also identify his parents and four brothers. Mark does not appear among those siblings.
From a research perspective, the conclusion is straightforward.
There is no credible evidence establishing a family relationship between Mark Gronowski and Rob Gronkowski.
The similar surnames create the search interest, but the available biographical information does not support a family connection.
