Lyubov Smolka (née Ruchkova; Ukrainian: Любовь Смолка-Ручкова; born 29 November 1952) is a Ukrainian former track and field athlete who competed in the 1500 metres for the Soviet Union. Born in Pavlohrad, Ukrainian SSR, she had her breakthrough performance in Moscow in 1980, taking second place in the 1500 m to Tatyana Kazankina, who broke the world record. Smolka was two seconds behind with 3:56.7 minutes, though this was enough to make her the second fastest woman ever at that point. Her time, as of 2016, still ranks her within the all-time top thirty athletes for the event.
