Leela Roy (née Nag; 2 October 1900 – 11 June 1970) was a leftist Indian woman politician and reformer, and a close associate of Netaji Subhash Chandra Bose.

She was born into an upper middle class Bengali Kayastha family in Goalpara district of Bengal Province and educated at the Bethune College in Calcutta, graduating in 1917.

In 1931, she began publishing the Jayasree Patrika, the first magazine edited, managed, and wholly contributed by women writers.

In 1941, when there was a serious outburst of communal rioting in Dhaka, she along with Sarat Chandra Bose formed the Unity Board and National Service Brigade.

Even before Gandhiji reached there, she opened a relief center and rescued 400 women after touring on foot 90 miles in just six days.

After the Partition of India, she ran homes in Calcutta for destitute and abandoned women and tried to help refugees from East Bengal.
