Elinor Jane Barker is a Welsh racing cyclist, who currently rides on the track for Great Britain and the Welsh Cycling backed Team USN, and on the road for Matrix Fitness Pro Cycling.

Barker is a two time world champion in women's team pursuit, having won the three rider version of the event in 2013 for Great Britain with Laura Trott and Dani King, and the extended four rider version in 2014, again with Trott, Katie Archibald and Joanna Rowsell. She is also a reigning European champion in the same event.

Barker took up cycling with the Maindy Flyers at the age of 10, as a way of getting out of swimming classes. She was recruited into British Cycling's Olympic Development Academy, but remained based in Wales until she completed her A-levels in 2013, after which she moved to Manchester to train full time at Manchester Velodrome.
