Swami Keshavashram ( Devanagari: केशवाश्रम्, ) was the fifth guru of the Chitrapur Saraswat Brahmin community,that is, the Fifth Mathādhipati(Head of the Chitrāpur Matha) of the community. His reign was from 1785 to 1823, a period of 38 years (42 years including his period as disciple of Swami Shankarāshram II). He became the head of the community after his teacher( guru) Swami Shankarāshram died in 1785.
Under his administration, the Chitrapur Math acquired land and property. He was able to consolidate the Sāraswat Community both in numbers(increased the number of followers) and in faith (weaned away many from Dvaita Vaishnava practises). He died in 1823 at Shirali. His samādhi(shrine) is located at Shirali.
