Marcus Dwayne Roberson (born October 4, 1992) is an American former professional football defensive back.

As a senior, he helped lead the St. Thomas Aquinas Raiders high school football team to a 15–0 record, a Florida Class 5A state championship, and the No.

As a freshman in 2011, he started the first ten games before suffering a season-ending injury against the South Carolina Gamecocks.

In 2012, he appeared in all 13 games, starting four; he recorded 23 tackles, 18 solo, had two interceptions, 12 pass breakups (which ranked second best in the Southeastern Conference), and a forced fumble.

On January 4, 2014, he announced he would forgo his final year of college eligibility and enter the 2014 NFL draft.

After the CFL canceled the 2020 season due to the COVID-19 pandemic, Roberson chose to opt-out of his contract with the Ottawa Redblacks on August 26, 2020.
