Miltiadis "Miltos" Tentoglou (Greek: Μιλτιάδης "Μίλτος" Τεντόγλου [miltiˈaðis te(n)ˈdoɣlu];[4] born 18 March 1998[5]) is a Greek long jump athlete, who is 14th in the all time lists, but one of the best in terms of achievements, as he is a double Olympic Champion with multiple World and European titles also to his name in a career which has brought him 11[6] gold medals.

[14][15] Tentoglou gained his first international experience at the age of 17, at the 2015 World Under-18 Championships in Athletics held in Cali, Colombia, where he placed fifth with a jump of 7.66 metres.

[16] Two months later, he won the silver medal at the World U20 Championships in Bydgoszcz, Poland for a leap of 7.91m, behind Cuban Maykel Massó (8.00 m).

The following month, Tentoglou was one of the youngest members of Hellenic expedition at the Summer Olympics in Rio de Janeiro, where he was, however, eliminated in the qualifications (7.64m).

In May 2021 at a meeting in Athens, Tentoglou landed at 8.60 metres, becoming the third-best European performer of all time, behind Robert Emmiyan and compatriot Louis Tsatoumas.

With just one centimetre separating the three medallists, it matched the 2012 edition for the closest ever World Indoor Championships long jump final.

In September 2024 he spoke out against the World Athletics Federation's intention to replace the wooden jumping board with a take off zone.
