Robert James Gronkowski is an American former football tight end who played in the National Football League (NFL) for 11 seasons. Nicknamed "Gronk", Gronkowski played nine seasons for the New England Patriots, then played his final two seasons for the Tampa Bay Buccaneers. Regarded as one of the greatest tight ends of all time, he is a four-time Super Bowl champion, a five-time Pro Bowl selection, a four-time first-team All-Pro selection, and was selected to the NFL 2010s All-Decade Team and NFL 100th Anniversary All-Time Team.

The tight end (TE) is an offensive position in American football, arena football, and Canadian football. It is a hybrid that combines the characteristics and roles of both an offensive lineman and a receiver. As part of the receiver corps, they play inside the flanks (tight), contrasted with the split end who plays outside the flanks (wide). Like offensive linemen, they are usually lined up on the offensive line and are large enough to be effective blockers. On the other hand, unlike offensive linemen, they are eligible receivers and potent weapons in a team's offensive schemes.
