The 2023 Herculis was the 37th edition of the annual outdoor track and field meeting in Monaco.

Held on 21 July at Stade Louis II, it was the ninth leg of the 2023 Diamond League – the highest level international track and field circuit.

At the meeting, Faith Kipyegon broke the women's mile world record, taking it from 4:12.33 to 4:07.64 and bringing it roughly in line with her earlier 1500 m world record at the 2023 Golden Gala.

The depth of the race made it unique among all other mile races, as continental records were also set for Africa, Oceania, North America, and South America.
