Prakashchandra Pandurang Shirodkar, (1941 – 6 May 2021), the eldest son of Pandurang Purushottam Shirodkar, was an Indian Indologist, archaeologist, and writer. His father, Pandurang Shirodkar, was a prominent freedom activist of Goa, and also served as the first speaker of the Goa, Daman and Diu Legislative Assembly under the Maharashtrawadi Gomantak Party.
