The men's outdoor doubles' was one of six lawn tennis events on the Tennis at the 1908 Summer Olympics programme. Nations could enter up to 6 pairs. The event was plagued by withdrawals, with only 12 teams competing of the 21 that entered. There were 24 players from 8 nations. The event was won by Reginald Doherty and George Hillyard after defeating James Cecil Parke and Major Ritchie in the final. Clement Cazalet and Charles P. Dixon took the bronze medal without a bronze-medal match due to the withdrawal of an entire quadrant of the bracket. All three medal pairs were British. It was the second medal sweep in the men's doubles, after the United States did it in 1904, and it was also the last time that the men's doubles gold medal match was contested by pairs representing the same nation until Tokyo 2021. Doherty became the first man to win multiple men's doubles medals and gold medals, having earned gold with his brother Laurence Doherty in 1900.

Six tennis events were contested at the 1908 Summer Olympics in London, United Kingdom. Indoor tennis events, on what were officially called 'covered courts', were held for the first time, along with the usual outdoor events. Women's events were contested, with women's singles and indoor women's singles. The indoor events were held at the covered courts of the Queen's Club and began on 6 May 1908, ahead of the official start of the Games while the outdoor tournament was played on grass courts at the All England Lawn Tennis and Croquet Club at Worple Road from 6 July through 11 July 1908. In total 50 players, 40 men and 10 women, competed. Five nations made their tennis debuts, while five more returned to competition for a total of ten nations. Two players, Les Poidevin and Wimbledon champion Anthony Wilding were nominated for Australasia but through administrative bungling they were not entered.
