Sudhindra Thirta (31 March 1926 – 17 January 2016), also referred to as Shri Sudhindra Thirtha Swamiji, was the legal and spiritual head (mathadipathi) of the Kashi Math and the twentieth successive person called the swamiji of guru parampara.

Sudhindra Thirtha attained Vrindavan on 17 January 2016 at Vyasa ashram, Haridwar.
As per the tradition of the math, to continue the guruparampara, on 7 July 1989, his Holiness initiated a vatu into sanyasa to be the 21st, and called him Raghavendra Thirtha. Due to internal strife Raghavendra was removed from the position and all rights in the math, with effect from 19 July 2000. Later, to continue the tradition and guruparampara of the math, it was necessary to initiate a new Shishya. Sudhindra theertha swamiji therefore initiated another vatu into sanyasa and named him as Samyamindra Thirtha swamiji on 20 June 2002 as the new successor. Thus Samyamindra become main disciple (patta shishya) & successor (uttaradhikari) of the math.
