Ülo Jõgi (12 March 1921, in Tallinn – 14 May 2007, in Tallinn) was an Estonian war historian who was active in the Estonian resistance against the Soviet occupation of Estonia.
On 11 December 1944, Jõgi (former member of Erna long-range reconnaissance group, organized by Finnish Army together with Nazi Germany) was arrested by the Soviet authorities, accused of spying for United Kingdom. Months later, he was sent to a Gulag labor camp in the Komi Republic, to the west of the Ural Mountains in the north-east of the East European Plain. He was exiled from the Estonian SSR for life, but was eventually released in 1970. He returned to Keila, Estonia, a year later. During his exile, he married Aili Jõgi, a fellow Estonian who had been deported in 1946 for having blown up the preceding monument to the Soviet Bronze Soldier in Tallinn.
In February 1997, Jõgi was awarded the Estonian Order of the Cross of the Eagle for his fight against Soviet occupation ("Freedom fighter of military merit") by the Estonian President Lennart Meri.
