Madhu Limaye, full name: Madhukar Ramchandra Limaye, was an Indian socialist essayist and activist, particularly active in the 1970s. A follower of Ram Manohar Lohia and a fellow-traveller of George Fernandes, he was active in the Janata government that gained power at the Centre following the Emergency. He, with Raj Narain and Krishan Kant was also responsible for the collapse of the Morarji Desai-led Janata government installed by that coalition, by insisting that no member of the Janata Party could simultaneously be a member of an alternative social or political organisation. This attack on dual membership was directed specifically at members of the Janata Party who had been members of the Jan Sangh, and continued to be members of the right-wing Rashtriya Swayamsevak Sangh (RSS), the Jan Sangh's ideological parent. The issue led to fall of the Janata government in 1979, and the destruction of the Janata coalition.

Ram Manohar Lohia was an activist in the Indian independence movement and a socialist political leader. During the last phase of British rule in India, he worked with the Congress Radio which was broadcast secretly from various places in Bombay until 1942.
