Henoc Muamba (born February 23, 1989) is a Congolese-Canadian former professional football linebacker who played in both the Canadian Football League (CFL) and National Football League (NFL). He was a two-time CFL All-Star, three-time CFL Divisional All-Star, and was named the CFL's Most Outstanding Canadian in 2017. In 2022, he won the Grey Cup with the Toronto Argonauts and was named the game's most valuable player (MVP) and Grey Cup Most Valuable Canadian, becoming the second player in history to earn both awards. He was also a member of the Winnipeg Blue Bombers, Indianapolis Colts, Montreal Alouettes, Dallas Cowboys, and Saskatchewan Roughriders.

He was selected first overall by the Blue Bombers in the 2011 CFL draft, becoming the first player from the St. Francis Xavier X-Men to be chosen first overall in the draft.

In the Canadian Football League’s Amateur Scouting Bureau final rankings, he was ranked as the third-best player for players eligible in the 2011 CFL draft, and first by players in Canadian Interuniversity Sport. On May 6, 2011, a Winnipeg Blue Bombers source leaked the Blue Bombers' intentions to select Muamba with the first overall pick in the 2011 CFL draft. To no surprise, Muamba was indeed selected first overall by Winnipeg in the draft and was signed to his first professional contract on May 30, 2011.

He played in his first professional game on August 26, 2011, against the Hamilton Tiger-Cats. He played mostly on special teams in his first year in the league and scored his first touchdown on a blocked punt return which he brought back 52 yards for the score on September 30, 2011, against the Montreal Alouettes. Muamba played in 11 regular season games in 2011 where he totalled 15 special teams tackles, one forced fumble, and one touchdown. He played in both post-season games, including his first Grey Cup appearance in the 2011 championship game, but the Blue Bombers lost to the BC Lions.

Muamba became a very significant part of the Bombers defence in 2012 as he recorded 65 tackles and three sacks while adding another 20 tackles on special teams. Muamba built upon the strong 2012 season he had with an even better 2013 season. He set a new career high with 106 defensive tackles (second most in the league), while also adding one quarterback sack and one interception. His outstanding 2013 campaign was recognized by the Blue Bombers as he was unanimously voted as the team's Most Outstanding Player, Most Outstanding Defensive Player and Most Outstanding Canadian. He won the Lew Hayman Trophy as the East Division's Most Outstanding Canadian. On February 5, 2014, Muamba was released by the Blue Bombers to pursue an NFL contract.

On February 6, 2014, Muamba signed with the Indianapolis Colts of the National Football League. He played in 13 regular season games with the Colts and recorded three solo tackles and two assisted tackles. He was waived on September 5, 2015.

On September 30, 2015, Muamba signed with the Montreal Alouettes nearing the end of the 2015 CFL season. Muamba played in four games for the Alouettes, contributing 14 tackles and one interception. On February 16, 2016, Muamba was released by the Alouettes to once again pursue his NFL interest.

Muamba signed with the Dallas Cowboys of the NFL on July 30, 2016. He was released by the Cowboys on the final 53-man cut down day September 2, 2016.
