Dewan Khan Bahadur P. Khalifullah (1888–1950),[1] was a politician of the Madras Presidency, British India, who served as the minister for public works in the short-lived ministry of Kurma Venkata Reddy Naidu from April–July 1937.

Born in 1888 in Tiruchi into a wealthy rice merchant's family, his birth name was Mohamed Pichai Rowther Ibrahim Khalifullah.

The family's ancestral home in Pakkali Street, Bheema Nagar was large, and it was not unusual for at least 50–100 guests to be served a meal there at any given day.

Other highlights in his political career include the membership of the Madras Presidency Legislative Council from 1930 to 1936, and a stint in 1937 as the Public Works Minister under the leadership of K. Venkata Reddy Naidu.

He was a vocal opponent of the introduction of compulsory Hindi lessons in the south, and with Periyar, flagged off the 100 Anti-Hindi Volunteers march in 1938.

Later on, though, he dissociated himself from the demand for a separate ‘Dravida Nadu’ by the Dravidian Movement as also Mohamed Ali Jinnah's move for partition.

In 1937, he spoke against the introduction of compulsory Hindi classes in the Madras legislature and later participated in the anti-Hindi agitation started by Periyar.
