The Capitan O'Brien class were three submarines built for the Chilean Navy in the late 1920s. They were similar to the contemporary British Odin class submarines, but mounted a larger 4.7 in (120 mm)/45 deck gun and were slightly smaller.
All boats were built by Vickers in Barrow-in-Furness and commissioned in 1929
The two Oberon class submarines purchased by Chile in the 1970s were also known locally as the O'Brien class.
