Pavel Vitalyevich Gayev (Russian: Павел Витальевич Гаев; 17 August 1901 – 5 October 1943) was a Soviet military intelligence officer, guards colonel, deputy commander of the 13th Guards Rifle Division (1943).
 Gayev was born on 17 August 1901 in Nizhny Tagil (Russian Empire) in a workers family. Initially, he only completed a two-year course of a zemstvo primary school in 1913. In 1918 he volunteered to serve in the Red Army were later he completed political courses of the Kharkov Military District (1921) and the Military Political School of the Kiev Military District (Kiev, 1923).

In 1928 he was selected to attend an officer training course known as Vystrel which he graduated from in 1929.
 In 1934 Gayev completed a course of the M. V.

 Upon completion of his mission in Poland, he served as the Red Army Intelligence Directorate officer (July–September 1939) and chief of military intelligence in the staff of the Odessa Military District (November 1939 - July 1941).
 According to archival documents Gaev on request of the Chief of the Red Army Intelligence Filipp Golikov conducted during this period a verification of intelligence reports from the Bucharest resident on the preparation of German invasion in the USSR.
 In the war period, Gayev was involved in combat operations from the end of July 1941, initially as chief of military intelligence in the staff of the 9th Army (1941-1942). This time 9th Army participated in the battle of Rostov (1941) and in the Barvenkovo–Lozovaya operation.
 In 1943 he graduated from a short course of the K. E.

In the division command he played a notable role in the liberation of Poltava and the battle of the Dnieper. Gayev was awarded the Order of the Red Banner for commanding the vanguard detachment in the successful crossing the Vorskla river which allowed the Soviets to regain control of the city of Poltava.
 On 5 October 1943 Gayev was killed in action on the battlefield (at the left shore of the Dnieper river near Kremenchuk) when commanding one of the river crossing operations in the battle of the Dnieper. For this operation he was awarded the Order of the Patriotic War, 1st Class (posthumously) for the outstanding personal commanding role in crossing the river Dnieper by the 13th Guards Rifle Division troops in early October 1943.
 Initially he was buried at the city cemetery of Poltava but later his tomb was moved to the newly established military memorial in Poltava's Ivan Kotliarevsky Park (1969).
 Pavel Gayev was the elder of three sons in his family. His father died when Pavel was eight and his mother moved to Yekaterinburg where she worked as a railway train conductor. 
 Middle brother Vasily V. Gayev (Russian: Василий Витальевич Гаев) (1904-?) also worked on the railroad in Nizhny Tagil. During the Great Purge Vasily was arrested and sent to the Gulag camps, later rehabilitated in 1962. The youngest brother in the family was Anatoly V. Gayev (Russian: Анатолий Витальевич Гаев) (1907-1954) who lived and died in Chelyabinsk.
 Pavel Gayev got married in late 1920th and his wife was Eugeniya I. Gayeva (Russian: Евгения Ивановна Гаева) (born in 1901). During the war she lived in Chelyabinsk, after the 1945 — in Kiev. Their son — Remar P. Gayev (Russian: Ремар Павлович Гаев) (born in 1930) was an officer of the Soviet Armed Forces.
 In the battles on these islands we suffered considerable losses. The deputy commander of the 13th Guards Rifle Division guards colonel P. V. Gayev was killed in action. I could not believe that this brave, strong-willed, enterprising officer is no longer with us. My irreplaceable deputy, my right hand, the fearless man the soldiers jokingly called enchanted against bullets. Sappers began to prepare for crossing the Dnieper. All boats, barrels, wickers, logs of burnt houses, fallen trees were mobilized in the village. The observation post of the division commander was next to our 34th Regiment command and control post. On the shore, despite the strong shelling of the enemy, the deputy division commander colonel Gayev was watching the preparation of the boats blithely strolling along the coast. It was a very impressive figure: tall, large build, with his gray-hairs fluttering in the wind. He reminded me of King Lear. Colonel Gayev walked along the coast as enchanted against shells and mines that reached from the right bank of the Dnieper, he stimulated sappers with a stick, collected soldiers who were free from duties, hurried to prepare the ferry. But in war, no one was insured. Colonel Gayev was killed by a shell projectile near the division сommand and control post.
