Cycling at the 1952 Summer Olympics – Men's track time trial

The men's track time trial at the 1952 Summer Olympics in Helsinki, Finland was held on July 31, 1952. There were 27 participants from 27 nations, with each nation limited to one competitor. The event was won by Russell Mockridge of Australia, the nation's first victory in the men's track time trial since 1932 and second overall (tying France for most of any nation). Marino Morettini's silver was Italy's first medal in the event; Raymond Robinson's bronze was South Africa's. France's three-Games podium streak ended.

Background
This was the sixth appearance of the event, which had previously been held in 1896 and every Games since 1928. It would be held every Games until being dropped from the programme after 2004. The only returning cyclist from 1948 was tenth-place finisher Onni Kasslin of Finland. Russell Mockridge of Australia had competed in the road race in 1948; he had won the sprint and time trial at the 1950 British Empire Games and taken second place in the 1951 sprint world championship. Marino Morettini was the amateur world record holder.

Czechoslovakia, Guatemala, Jamaica, Japan, Romania, and the Soviet Union each made their debut in the men's track time trial. France and Great Britain each made their sixth appearance, having competed at every appearance of the event.

Competition format
The event was a time trial on the track, with each cyclist competing separately to attempt to achieve the fastest time. Each cyclist raced one kilometre from a standing start.
