Idar State  or Edar (Gujarati: ઇડર; Hindi: इडर), was a princely state of India during the time of the British Raj. It was the most important state of the Mahi Kantha Agency, within the Gujarat Division of Bombay Presidency.
Idar State had an area of 1669 km², and a population (1901) of 168,557, showing a decrease of 44% in the decade as the result of famine. The estimated gross revenue was £29,000 and the tribute to the gaekwar of Baroda, £2000. In 1901 the raja and his posthumous son both died, and the succession devolved upon Pratap Singh of Idar (q.v.) of Jodhpur.
The line of railway from Ahmedabad through Parantij runs mainly through this state. Much of the territory is held by kinsmen of the raja on feudal tenure. The products are grain, oil-seeds and sugar-cane. The town of Idar is 64 m. N.E. of Ahmedabad. Pop. (1901) 7085. It was formerly the capital, but Ahmednagar (to the east of Himatnagar, pop. 3200) was the capital by the end of the British Raj.
In 1941 Idar had a population of 307,798.
Idar State was founded in the 13th century and was ruled by Rajputs. In 1791, it was split into five states: Idar, Ahmadnagar, Morasa, Baad (also called Bayar) and Soor. In 1821, Morasa was absorbed by Ahmadnagar. In 1826, Baad absorbed by Idar and Ahmadnagar. In 1843, Idar was reunited.
In 1924 Idar was made part of the Western India States Agency. It was transferred to the Rajputana Agency in the early 1940s. )n 10 June 1948 Idar became part of the Indian Union. In 1949 it was dissolved and split between Sabar Kantha district and Mehsana district which were at that point in Bombay State. Both these districts were included in Gujarat when it was formed in 1960.
