Thomas Carlisle Livingstone-Learmonth (5 January 1906 – 24 April 1931) was a British hurdler. He competed at the 1928 Olympics in the 400 metres hurdles and finished in fifth place.

The career of Livingstone-Learmonth was overshadowed by Lord Burghley, who beat him in the 440 yd hurdles at all 1926–1928 AAA Championships. Earlier in 1925 Livingstone-Learmonth set a British record in the 220 yd hurdles, but Burghley has bettered it within three weeks. In the semifinals of the 1928 Olympics, Livingstone-Learmonth set another British record in the 400 m hurdles, at 54.0 s, but it was bettered next day by Burghley in the final. Livingstone-Learmonth died of meningitis aged 25 while on a diplomatic mission in Sudan.^[1]

His grandfather was Thomas Livingstone Learmonth, an early European settler of Australia.
