SM UC-8 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat had been ordered by November 1914 and was launched on 6 July 1915. She was commissioned into the German Imperial Navy on 5 July 1915 as SM UC-8. Mines laid by UC-8 in her one patrol are not known to have sunk any ships. UC-8 ran aground on the Dutch coast near Terschelling on 4 November 1915. Interned by the Dutch, UC-8 was purchased and commissioned into the Dutch Navy as HNLMS M 1. The submarine was broken up in 1932.
