The 2023 European Athletics Indoor Championships was held from 2 to 5 March 2023 at the Ataköy Arena in Istanbul, Turkey, the first time the event took place in this country although the venue did stage the 2012 World Indoor Championships for which this 7000-seater was specifically built. The four-day competition was held during the centenary year of the Republic of Turkey, and featured 13 men's and 13 women's athletics events over three morning and four afternoon sessions.
