James Dasaolu (born 5 September 1987) is a retired British track and field athlete who specialised in the 100 metres.

Born in south London to Nigerian parents, Dasaolu did not take up sprinting seriously until he was 18 when he began a leisure management degree at Loughborough.

[5] The 2008 season saw Dasaolu rise up the national rankings and introduced to the UK Athletics warm weather training camp.

[10] He began 2013 by winning a silver medal at the 2013 European Athletics Indoor Championships in the 60 metres, running a personal best of 6.48 seconds in the final, finishing centimetres behind champion Jimmy Vicaut.

On 13 July at the British trials, Dasaolu ran a personal best of 9.91, the second fastest time ever by a Briton behind Linford Christie.

In the final of the Grand Prix, Dasaolu won with a time of 6.50 but pulled up 20 m from the line after a slight tear in his thigh muscle, causing him to give up his automatic selection place for the World Indoor Championships and focus on the outdoor season instead.
