William Tayler (1808–1892) was a civil servant of the East India Company who lived in India from 1829 until 1867. He became commissioner of Patna in 1855 and in 1857 was involved in the suppression of the 1857 Sepoy Rebellion. His measures against the local people were regarded as excessively harsh by his superiors, and he was suspended and given an appointment of lower rank.
