The Setesdal Line (Norwegian: Setesdalsbanen) was a railway between Kristiansand and Byglandsfjord in southern Norway, 78 km (48 mi) long.

Stations along the line included Mosby, Vennesla, Grovene (Grovane), Iveland and Hægeland.

Today, only the stretch between Grovane and Røyknes of the original line is preserved as a heritage railway.

The 6 km (3.7 mi) line between Beihølen and Grovane was, however, preserved by local enthusiasts.

Rail passengers had to change trains at Grovane Station from 1938 to 1962 due to different track widths, narrow-gauge to normal gauge.
