Valentin Vasiliyevich Bondarenko (Ukrainian: ???????? ?????????? ??????????, Russian: ???????? ?????????? ??????????; 16 February 1937 – 23 March 1961) was a Soviet fighter pilot selected in 1960 for training as a cosmonaut.
He died as the result of burns sustained in a fire during a 15-day low-pressure endurance experiment in Moscow.
The government concealed the death, along with Bondarenko's membership in the cosmonaut corps, until 1980.
A crater on the Moon's far side is named after him.
