Ingetorpssjön, Natural lake in Västra Götaland, Sweden.

Ingetorpssjön is a lake in Västra Götaland surrounded by forests and rolling hills with clear waters. The shoreline features natural vegetation and connects to several maintained trails through the surrounding landscape.

A burial ground from the 5th century lies beside the lake, with 15 grave mounds, 11 of them accompanied by raised stones bearing no inscriptions. It was excavated in 1913, but gravel surfacing had already damaged the mounds, so the dig added little new knowledge. A memorial stone in the rock face along the road records that the Kongelf–Kyrkeby road was rerouted in 1870.

The lake's name appears in two forms, Ingetorps sjö and Ingetorpssjön, both referring to the farm of Ingetorp. On its shore lie 15 grave mounds from the 400s, 11 of them with raised stones bearing no inscriptions; the site was excavated in 1913. A memorial stone in the rock face along the road recalls that the Kongelf–Kyrkeby road was rerouted in 1870.

The lake lies between Kode and Kareby, just west of the E6 motorway, and a bathing spot sits by the deep water. A memorial stone in the rock face along the road records that the Kongelf–Kyrkeby road was rerouted in 1870. The former rest area on the old Riksväg 2/E6 closed when the motorway was built around 1972. Svartedalens nature reserve and Ingetorps golf course are next to the lake.

Ingetorps sjö is one of the few Swedish lakes where freshwater mussels live, a sign of its very clean spring-fed water. A memorial stone in the rock face along the former road notes that the Kongelf–Kyrkeby road was rerouted in 1870.
