Arthabaska (French pronunciation: [aʁtabaska]) is a provincial electoral district in the Centre-du-Québec region of Quebec, Canada that elects members to the National Assembly of Quebec. It notably includes municipalities of Victoriaville, Plessisville, Princeville and Saint-Christophe-d'Arthabaska.
It was created for the 1890 election from a part of Drummond-Arthabaska electoral district.
In the change from the 2001 to the 2011 electoral map, Arthabaska lost Sainte-Hélène-de-Chester and Chesterville to the newly created Drummond–Bois-Francs electoral district, but gained nine municipalities from Lotbinière, which ceased to exist.
The seat was represented by Eric Lefebvre (CAQ) until he resigned on 18 March 2025 to run for the partially-overlapping federal riding of Richmond-Arthabaska. A by-election was held on 11 August 2025, which Alex Boissonneault (Parti Québécois) won.
