Sidney Arthur Taylor Rowlatt, KCSI (20 July 1862 – 1 March 1945) was an Anglo-Egyptian barrister and judge, remembered in part for his presidency of the sedition committee that bore his name, created in 1918 by the imperial government to subjugate and control the independence movement in British India, especially Bengal and the Punjab. The committee gave rise to the Rowlatt Act, an extension of the Defence of India Act 1915.
