The Market towns of Telemark and Aust-Agder counties (Norwegian: Kjøpstedene i Telemark og Aust-Agder fylker) was an electoral district for parliamentary elections in Norway. It comprised the market towns (Norwegian: kjøpsteder) of Brevik, Kragerø, Notodden, Porsgrunn and Skien in Telemark county and Arendal, Grimstad and Risør in Aust-Agder county. The district was established ahead of the 1921 Norwegian parliamentary election following the change from single member constituencies to plural member constituencies in 1919.
