Sangli State was one of the 11-gun salute Maratha princely states of British India. It was under the Kolhapur-Deccan Residency in the Bombay Presidency, and later the Deccan States Agency.

The Principality of Sangli covered an area of 2,880 square kilometers and had a population of 226,128 in 1901, while the population of the town itself was 16,829 in that year.

The capital of the state was Sangli. The city derives its name from "Saha Galli" ("Six Lanes" in Marathi).

Sangli was part of Maratha Empire, for it had been one of the Southern Maratha Jagirs. However, there are no direct references mentioning Sangli before 1801. During the time of Chhatrapati Shivaji, Sangli, Miraj and surrounding areas were captured from the Mughal Empire. Until 1801, Sangli was included in the Miraj Jagir. The First Chintamanrao Appasaheb Patwardhan established a different principality with Sangli as the capital city.

On 5 May 1819 Sangli State became a British protectorate. Its territory was widely scattered among other native states and British districts.

The last ruler of Sangli was Capt. HH Shrimant Raja Saheb Sir Chintamanrao II Dhundirajrao Appasaheb Patwardhan. Sangli joined the Dominion of India on 19 February 1948 and is currently a part of the state of Maharashtra.

The rulers of Sangli State were Hindu and belonged to the Patwardhan dynasty. They used the title of 'Rao'. The last ruler adopted the title 'Raja'
