Krishnacharya Purnaiah (1746 – 27 March 1812), popularly known as Dewan Purnaiah, was an Indian administrator, statesman, and military strategist who served as the first dewan of Mysore from 1782 to 1811. He was instrumental in the restoration of the rule of the Kingdom of Mysore to the Wadiyar dynasty. After the death of Tipu, he continued to advice Lakshmi Devi, the queen regent to the newly installed monarch Krishnaraja Wodeyar III.

Purnaiah was known for his accounting skills, prodigious memory, and proficiency in several languages. He was also a wartime military commander while serving under Tipu. After Tipu's defeat, he served as the dewan to Krishnaraja Wodeyar III. Wodeyar was educated and trained by Purniah in his early years.^[1]
