Sri Siddharameshwar Maharaj (Marathi: श्री सिद्धरामेश्वर महाराज; Kannada: ಶ್ರೀ ಸಿದ್ಧರಾಮೇಶ್ವರ್ ಮಹಾರಾಜ್ ) (1888–1936) was a guru in the Inchagiri Sampradaya founded by his guru Shri Bhausaheb Maharaj, a branch of the Navnath Sampradaya, the 'Nine Masters' tradition in India. He was the Guru of Nath teachers Sri Nisargadatta Maharaj, Sri Ranjit Maharaj, and Sri Kadsiddheshwar Maharaj.
Siddharameshwar was born in 1888 in the village Pathri, Solapur, India. Since his childhood he was very intelligent and had very sharp imbibe abilities. In 1906 he was initiated by his guru 'Shri Bhausaheb Maharaj' in Inchagiri in Karnataka India, who taught mantra meditation as the way to reach Final Reality. He was one of the contemporaries of Sri Ramana Maharshi.
In 1920 Siddharameshwar started to set out on "the Bird's Path", the fast way to attain realization, six years after Bhauhaseb maharaj had died. His fellow-students opposed, but eventually he succeeded by himself.
Siddharameshwar died on November 9, 1936 (Ekadashi, 11th day in the later half Ashwin), at the age of 48, giving his understanding to his disciples. It is said that dozens of his disciples became self-realized through his clear and lucid teaching. His samadhi shrine today is located at Banganga, Walkeshwar in Mumbai.
Atma Vidya (Self-Knowledge") is the central theme in Siddharameshwar Maharaj's teachings. In Master Key to Self-Realization he describes how the teaching of Vedanta is transmitted to a student. It starts with the meeting with a guru, who tells about the teachings. Thereafter a mantra is being used by the student to meditate and make the mind more receptive. Then the guru explains the teaching further, which has to be realized experientially by the student.
