Sergei Ovchinnikov

Sergei Anatolyevich Ovchinnikov (; 25 January 1969 – 29 August 2012) was the head coach of the Russia's National Women Volleyball Team.

Sergei's coaching career began in 1998 when his former teammate Sergei Shlyapnikov invited him to join the coaching staff of Neftyanik (Yaroslavl). In 2001, he joined the staff of Neftyanik (Ufa). The reason for the suicide remains unknown, although it was pointed out that Russian media heavily criticized Ovchinnikov for the failure at the Olympic Games in London, where his team was considered as the leading medal contenders but lost in the dramatic quarter-finals to eventual winners Brazil after squandering six match points.

On 6 September 2012, Ovchinnikov was buried in his home city of Yaroslavl.
