Svetlana Styrkina (Russian: Светлана Павловна Стыркина-Мощенок; née Moschenuk; born 1 January 1949) is a Belarusian former middle-distance runner for the Soviet Union.

[1][2] Born in Mogilev, Styrkina rose to be one of the world's top 800 metres runners in the late 1970s.

[3] She achieved her lifetime best of 1:56.44 minutes in the women's 800 metres final at the 1976 Montreal Olympics, but this was only enough for fifth place as it was the fastest race ever at that point, with the winner Tatyana Kazankina breaking the world record.

[5] She also helped set a world record in 1976, running a time of 3:29.06 minutes in a mile relay race alongside Inta Kļimoviča, Natalya Sokolova and Nadezhda Ilyina.

[9] After retiring from competition she went into coaching, with double Olympic champion Svetlana Masterkova among her charges.
