AG 12 was a Russian submarine of Holland 602GF/602L type (AG = Amerikansky Golland), 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 April 3, just prior to the German landing there. These submarines had good sea going qualities and were easy to handle.
