Tresfjorden (English: Tres Fjord)[1][2][3] is a fjord in Vestnes Municipality in Møre og Romsdal county, Norway.

The village of Vestnes sits at the mouth of the fjord (on the west side) and the village of Vikebukt sits at the mouth of the fjord (on the east side).

The village of Tresfjord is located at the southern end of the fjord.

[4] European route E39 runs along the northwest shore of the fjord, and European route E136 approaches the fjord from the east and crosses it over the Tresfjord Bridge.

The bridge opened in 2015, crossing the northern part of the fjord just south of the villages of Vestnes and Vikebukt.
