1991 Soviet Athletics Championships

The 1991 Soviet Athletics Championships was the 63rd and final edition of the national championship in outdoor track and field for the Soviet Union. It was held on 10–13 July at Republican Stadium in Kyiv, Ukrainian SSR. The competition was held within the 1991 Soviet Spartakiad. A total of 42 events were contested over four days. The marathon competition was held earlier on 21 April in Bila Tserkva.

The competition did not receive interest from several of the nation's top athletes, including Sergey Bubka, and audience attendance was also low. No team score was assigned for the Republics of the Soviet Union, as had been done in previous years. The championships formed part of the qualification for the Soviet team at the 1991 World Championships in Athletics. The highlight performance was Lyudmila Narozhilenko's Soviet national record of 12.28 seconds in the women's 100 metres hurdles. This made her the third fastest women ever in the event (after Bulgarians Yordanka Donkova and Ginka Zagorcheva) and remains one of the fastest performances of all time for the event.

This was the final Soviet Athletics Championships as the dissolution of the Soviet Union occurred in December that year. After this point, the newly independent republics began to hold their own national championships. Given the organisational disarray, the former Soviet states sent a Unified Team at the Olympics in 1992, which was selected through the 1992 CIS Athletics Championships – the last time the former Soviet countries held a united athletics event.
