Antonio Tavaris Brown Sr. (born July 10, 1988), nicknamed "AB", is an American former professional football wide receiver who played in the National Football League (NFL) for 12 seasons. During his first nine seasons with the Pittsburgh Steelers, Brown developed a reputation as one of the greatest receivers of his era, but his career has also been marked by various controversies.

Brown played college football for the Central Michigan Chippewas, twice earning first-team All-American honors as a punt returner, and was selected by the Steelers in the sixth round of the 2010 NFL draft. With Pittsburgh, Brown led the league twice in receiving yards, twice in receptions, and once in receiving touchdowns. He also earned seven Pro Bowl selections, including six consecutive, and four consecutive first-team All-Pro selections.

Amid conflict with the Steelers, Brown was traded to the Oakland Raiders in 2019, but was released before the start of the season following several off-the-field incidents. He later signed with the New England Patriots, but appeared in only one game before being released amid a sexual assault investigation. Brown returned to the NFL midway through the 2020 season with the Tampa Bay Buccaneers, where he was a member of the team that won Super Bowl LV. He was released near the end of the following season after leaving the field during a game.

Following the end of his playing career, Brown was the majority owner of the Albany Empire of the National Arena League (NAL) in 2023, a tenure that saw the team fold the same year.

Brown is the son of "Touchdown" Eddie Brown and Adrianne Moss. Brown's father played as a wide receiver for the Albany Firebirds in the Arena Football League, and was named the best player in the league's history in 2006.

Brown attended Miami Norland High School in Miami, Florida, where he played football. In football, Brown played running back, quarterback, wide receiver, and punt returner for the Vikings. He was a two-time Class 6A all-state selection and was also named North Athlete of the Year at 2005 Miami-Dade Gridiron Classic. Coming out of high school, Brown applied to Florida State University. His admission was denied over academic concerns.

After attempting to attend Alcorn State University, he decided to enroll at North Carolina Tech Prep. Playing in just five games at quarterback, Brown passed for 1,247 yards and 11 touchdowns, while rushing for 451 yards and 13 touchdowns. Once he finished his lone season at North Carolina Tech Prep, he received a scholarship to play at Florida International University, but he was expelled before the season for an altercation with security. Brown then began reaching out to wide receivers coach Butch Jones at West Virginia University, since he had been highly recruited by him. After learning that Jones had left West Virginia to become the head coach at Central Michigan University, Brown enrolled at the school and started his college football career as a walk-on freshman.

Brown attended and played college football for the Central Michigan Chippewas from 2007 to 2009.
