The American Holland-class submarines, also AG class or A class, were Holland 602 type submarines used by the Imperial Russian and Soviet Navies in the early 20th century. The small submarines participated in the World War I Baltic Sea and Black Sea theatres and a handful of them also saw action during World War II.

The AG type was designed by John Philip Holland at Electric Boat Company. The design was known as Holland 602GF/602L, which was very similar to the American H class. The Russian abbreviation "AG" comes from "Amerikansky Golland" ("American Holland"). In 1916, the Russian Naval Ministry ordered 11 units.

The boats were built at Barnet Yard in Vancouver, British Columbia, Canada as knockdown kits. The kits were transported by ship to Vladivostok and over the Trans-Siberian Railroad to European Russia. The boats were assembled at the Baltic Shipyard in Saint Petersburg and its subsidiary in Nikolayev by the Black Sea (now Mykolaiv, Ukraine). Like some of the British H-class boats (of the same design), they were equipped with Fessenden transducers, an early form of sonar.
