The 2021 Louisiana's 2nd congressional district special election was held on March 20, 2021, with a runoff being held on April 24, 2021.

On November 17, 2020, incumbent Democratic representative Cedric Richmond announced that he would resign from the United States House of Representatives to serve as the director of the Office of Public Liaison and as a Senior Advisor to Joe Biden. He did so on January 15, 2021, and took his new job when Biden assumed office on January 20, 2021. When congressional seats in Louisiana become vacant, the governor has the ability to call a special election at any time. The special election to fill Louisiana's 2nd congressional district took place on March 20, and a runoff was held on April 24. Troy Carter won the runoff election on April 24, 2021 against fellow Democrat Karen Peterson.

In the jungle primary, Carter and Peterson took first and second place with 36% and 23% of the vote, while Chambers took third place with 21%.
