Eliud stunned the world in October when he became the first man ever to run a marathon in under two hours. The record-breaking run was accomplished just six months after he also won the London Marathon for the fourth time.
A highly decorated distance runner, he has also won Olympic marathon gold at the Rio Olympics in 2016 and World Championship 5000m gold on the track.
He is the fourth long-distance runner to win this award, the last being Australian Ron Clarke in 1965.
Eliud faced tough competition for the award with gymnast Simone Biles, captain of the South Africa rugby team Siya Kolisi, footballer Megan Rapinoe, cricketer Steve Smith and golfer Tiger Woods also nominated in the same category before the public voted for their winner via the BBC Sport website.
The World Sport Star of the Year award will be presented to Eliud at the BBC Sports Personality of the Year awards, which take place at the P&J Live arena in Aberdeen on Sunday 15 December and will be broadcast live on BBC One from 7pm.
