AG-11 was a Russian AG-class (AG = Amerikansky Golland) submarine, which served in the Gulf of Finland during World War I.

During World War I Russian and British submarines operated from bases in Finland. The Russian submarines of Holland type (AG-11, AG-12, AG-15 and AG-16) were scuttled in the harbor of Hanko on 3 April 1918 just prior to the German landing there. These submarines had good sea going qualities and were easy to handle.
