Hafslo is a village in Luster Municipality in Vestland county, Norway.

The village is located on the northern shore of the lake Hafslovatnet, about 3 kilometres (1.9 mi) northwest of the village of Solvorn which sits on the shores of the Lustrafjorden.

The village of Sogndalsfjøra lies 15 kilometres (9.3 mi) to the south; the village of Gaupne lies about 15 kilometres (9.3 mi) to the north; and the village of Veitastrond lies about 25 kilometres (16 mi) to the northwest.

The Norwegian County Road 55 runs through the village on its way from Sogndalsfjøra to Gaupne.

The second element of the name comes from the old word ló meaning "meadow", probably due to the excellent farming areas nearby.
