Jasdan State was a princely state in Saurashtra during the British Raj. Its last ruler signed the accession to the Indian Union on 15 February 1948. The capital of the state was in Jasdan town.

Jasdan state was founded in 1665 when Vika Khachar defeated the Khumans of Kherdi. In 1807, after its ruler Vajsur Khachar came to an agreement with the British and the Gaikwar, it became a British protectorate. Later in the 19th century Jasdan became part of the Kathiawar Agency of the Bombay Presidency.

Jasdan was the biggest kathi state in British India issuing its own postage stamps.

The rulers of the state bore the title 'Darbar'.
