Manathoor Devasia Valsamma (born 21 October 1960) is a retired Indian athlete.

She started her athletics career during school days though she only took it more seriously when she moved to Mercy College,[1] Palakkad, for further studies.

This made her the second woman athlete to win an Asian Games gold for India, after Kamaljit Sandhu (400 metres-1974).

For the first time in the history, the Indian women team entered the finals in the Los Angeles Olympics, 1984 and finished in the seventh position.

Valsamma took part in World Cup meets in Havana, Tokyo, London, the Asian Games editions of 1982, 86, 90 and 94 and in all the Asian Track & Field meets and SAF Games, leaving her mark in each and every competition.
