Sugathakumari (22 January 1934 – 23 December 2020) was an Indian poet and activist, who was at the forefront of environmental and feminist movements in Kerala, India.

Sugathakumari was born in Aranmula on 22 January 1934 in the modern day southern Indian state of Kerala (then in the Kingdom of Travancore).

Her father Keshava Pillai, known as Bodheswaran, was a famous Gandhian thinker and writer, who was involved in the country's freedom struggle.

[5] In 1968, Sugathakumari won the Kerala Sahitya Akademi Award for Poetry for her work Pathirappookal (Flowers of Midnight).

Her poem Marathinu Stuthi (Ode to a Tree) became a symbol for the protest from the intellectual community and was the opening song of most of the Save Silent Valley campaign meetings.

Three women led by social activist and artist G. Geetha, demanded a probe into the rape of a Dalit inmate woman by two counselors and the hostel warden of 'Abhaya' in 2002.

The Kerala government declared Sugathakumari's ancestral house, Vazhuvelil Tharavadu, as a protected monument on her 84th birthday.

[29] Sugathakumari died on 23 December 2020, due to complications from COVID-19 during the COVID-19 pandemic in India, at the Government Medical College, Thiruvananthapuram, thirty days short from her 87th birthday.
