The new party is called the Lovers' Green-Globalist Godfree-Humanist Party of India.
Founder Biswanath Ramachandra Champa Swapnaji Taslima Voltaire has been promoting inter-caste, dowryless marriages for more than 20 years.
The 58 year-old former teacher, from Bhubaneswar in Orissa, said: "This alone can bring change in society."
He earlier formed the Anti-caste Marriage One-child Family Organisation of India, which has so far solemnised 1,693 inter-caste marriages.
All the marriages are performed in a simple manner, with the couples exchanging garlands in the presence of members of the group.
People joining the organisation are required to change their names in such a manner that nobody will be able to figure out to which religion or caste they originally belonged.
Mr Voltaire, who himself went through what is commonly called a love marriage, in India in 1966, said the new party would only offer election tickets to those who have married, or plan to marry, only for love.
He told, "Those who love and get married are courageous. Love has power. Only those who marry after first falling in love can bring changes in society."
