The Fleet Problems were a series of United States Navy exercises conducted in the interwar period, later resurrected by the United States Pacific Fleet around 2016.

The first twenty-one Fleet Problems — labeled by Navy leadership as Fleet Problem I through Fleet Problem XXI — were conducted between 1923 and 1940. The culmination of the Navy's annual training maneuvers, they were unscripted, free play exercises involving large concentrations of ships, airplanes, and troops.^[1] Fleet Problem XXII, scheduled for 1941, was canceled because of rising tensions with Japan on the eve of the US's entry into World War II.^[2] Following the outbreak of war, Fleet Problems underwent a prolonged hiatus, with other names being used to describe large American naval exercises. However, the term was revived in the 21st century under Admiral Scott H. Swift, with Fleet Problem XXIII through XXVIII taking place in the Pacific from 2016 on.^[3] Since 2018, the US Navy has not publicly used the historical roman numeral numbering scheme.
