The 1983 Cantabrian regional election was held on Sunday, 8 May 1983, to elect the 1st Regional Assembly of the autonomous community of Cantabria. All 35 seats in the Regional Assembly were up for election. The election was held simultaneously with regional elections in twelve other autonomous communities and local elections all throughout Spain.

The Parliament of Cantabria is the unicameral legislature of the autonomous community of Cantabria. It consists of 35 members called "deputies" which are freely elected by the citizens of the region. The Parliament convenes at the Saint Raphael Hospital, an 18th-century building in the city of Santander rehabilitated in the 1980s to house the Regional Assembly.
