Louis Plamondon MP (born July 31, 1943) is a Canadian politician who has served as a member of Parliament (MP) since his election in 1984. He represents Bécancour—Nicolet—Saurel (formerly known as Bas-Richelieu—Nicolet—Bécancour and Richelieu) and briefly served as the 38th speaker of the House of Commons in an interim capacity in 2023. Plamondon is a member of the Bloc Québécois; he was first elected as a Progressive Conservative (PC), until leaving the PC caucus in 1990.

Plamondon has won his seat in twelve consecutive federal elections, winning twice as a Progressive Conservative before becoming a founding member of the Bloc Québécois in 1990, after which he has been re-elected ten more times. He, along with six other Bloc MPs, resigned from the Bloc's caucus to sit as an independent MP on February 28, 2018 citing conflicts with the leadership style of Martine Ouellet. He rejoined the Bloc Québécois caucus on September 17, 2018.

In November 2025, Plamondon became the MP with the longest continuous service in Canadian history, with 15,059 days, exceeding the record of Sir Wilfrid Laurier. As the longest-serving current member of the House of Commons, Plamondon is Dean of the House, and also holds the record as Canada's longest-serving dean.
