The 1966 European Indoor Games were the first edition of what later became the European Athletics Indoor Championships.

These games took place on 27 March 1966 at Westfalenhalle, Dortmund, a city of West Germany.

It was the only edition held on a single day – since 1967 the duration was extended to two days and since 1992 to three.

The track used for the championships was 160 metres long.
