The Chilean submarine O'Brien (S22) was an Oberon-class submarine in the Chilean Navy. Unlike her sister ship Hyatt, O'Brien was built new for the Chilean Navy. She was in service from the mid-1970s until the mid-2000s, but both she and Hyatt were replaced by the newer Thomson-class submarines Thomson (SS-20) and Simpson (SS-21).

Her namesake was John Thomond O'Brien (1786-1861), the Irish-born liberator of Chile and Argentina .^[1]
