Sunk after 12 February 1945 in the Gulf of Finland south of Hanko, in approx. position 59.30N, 23.00E, by a mine in the barrage Vantaa 3 laid by the Finnish minelayers Louhi and Routsinsalmi on 12 January 1945. 57 dead (all hands lost).

In late 2012 the Finnish diving team 'Badewanne', after 10 years of searching, reported they had found both U-676 and U-745 in the Gulf of Finland south of Hanko. Both boats went missing in early 1945 with all hands lost. The boats were apparently lost in the mine barrage Vantaa 3 laid by the Finnish minelayers Louhi and Routsinsalmi on 12 Jan 1945.

The boat claimed two Soviet planes (an Il-2 and a Pe-2) shot down near Ösel island in the Baltic. The U-boat was acting as a convoy flak escort.
1 recorded attack on this boat.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-676 did not suffer any casualties (we know of) until the time of her loss.
