Finsland is a former municipality in the old Vest-Agder county, Norway. The 118-square-kilometre (46 sq mi) municipality existed from 1838 until its dissolution in 1964. The administrative centre was the village of Finsland where Finsland Church is located. The municipality generally encompassed the northern part of the present-day municipality of Kristiansand in what is now Agder county.

In 2016, there were 182,701 inhabitants, around 3.5% of the total population of Norway. Its area was about 7,277 square kilometres (2,810 sq mi).
