Ammembal Subba Rao Pai (19 November 1852 – 25 July 1909) was a leading lawyer of Mangalore, India.

He helped shape the future of Dakshina Kannada District and of the GSB community in Karnataka.

In his office room was prominently displayed a portrait of Ashwini Kumar Dutta, one of the heroes of nationalist Bengal, one word from whom could make the traders of his native town refuse to sell even a yard of cloth to European officers, including the collector of the district.

In 1891, four teachers, whom he had met in Madras,(now Chennai) approached him with a proposal to start a school in Mangalore and thus was born the Canara High School, on 22 acres of land donated by Upendra Pai, his father in Mangalore.

Among his important contributions to the GSB (Gaud Saraswat Brahmin) community was the setting up of the ‘Poor Boys Education Fund’ (which became ASRP Memorial Fund as per the decision taken at a meeting of the GSB community held in the Bhuvanendra Hall on 1 August 1909) under the aegis of Gowda Saraswath Brahman Parishad, of which he was one of the founders.

Throughout his life, Ammembal Subba Rao Pai suffered from a severe gout, an affliction to which he finally succumbed on 25 July 1909.
