Tirunesh Dibaba (Oromo: Xirunesh Dibaabaa, Amharic: ጥሩነሽ ዲባባ ቀነኒ; born 1 June 1985) is an Ethiopian long-distance runner athlete who competes in long-distance track events and international road races. She has won three Olympic track gold medals, five World Championship track gold medals, four individual World Cross Country (WCC) adult titles, and one individual WCC junior title. Tirunesh was the 5,000 metres (outdoor track) world record holder until 2020. She is nicknamed the "baby-faced destroyer."

At the 2005 IAAF World Championships in Helsinki, Finland, Tirunesh became the first woman to win the 5000 m and 10000 m at the same championship. She is the one of two women (the other Sonia O'Sullivan) who won the short and long course World Cross Country title at the same championship (2005 in Saint-Galmier, France). With her 2003 World championship title, she became the youngest World Champion at the age of 18 years and 90 days.

Tirunesh comes from a sporting family of several Olympic medalists, which includes her sisters Genzebe, Ejegayehu and Anna, and her cousin, Derartu Tulu. The matriarch of the Dibaba athletics dynasty, Tirunesh is the most decorated of the family.
