Tetyana Apaycheva (née Khamitova, Divorced Samolenko and Dorovskykh, Ukrainian: Тетяна Володимирівна Апайчева, née Хамітова, born 12 August 1961) is a Ukrainian retired middle-distance runner who represented the Soviet Union until 1991, the Unified Team in 1992, and later Ukraine.

As Tetyana Samolenko, she was the leading female middle-distance runner of the late 1980s.

After giving birth in 1990, she returned to competition in 1991 competing as Tetyana Dorovskikh, and retained her World title at 3000 metres.

Her previous performances were impugned when she tested positive for drug use in June 1993, which effectively brought an end to her career.
