Nagod State (also known as 'Nagode' and 'Nagodh') was a princely state of colonial India, located in modern Satna district of Madhya Pradesh. The state was known as 'Unchahara' after Unchehara, its original capital until the 18th century.

The Parihar Rajputs of Nagod were descendants of Imperial Parihar dynasty. Balabhadrasimha, who was the ruler of Nagod and belonged to Parihara family. Indian Archaeology Review 2000-’01 published by the Archaeology Survey of India identifying the Nagod dynasty as Parihara at page 166.

In 1344, the city of Uchchakalpa, present-day Unchahara, was founded by Rajput Raja Veerraj Judeo when he seized the fort of Naro from "the others". In 1720 the state was renamed Nagod after its new capital. In 1807 Nagod was a tributary to Panna and was included in the sanad granted to that state. In 1809, however, Lal Sheoraj Singh was recognized and confirmed in his territory by a separate sanad granted to him. Nagod State became a British protectorate after the treaty of Bassein in 1820. Raja Balbhadra Singh was deposed in 1831 for murdering his brother. The state fell into debt and in 1844 the administration was taken over by the British owing to economic mismanagement. The ruler was loyal during the Indian Mutiny in 1857 and was granted the pargana of Dhanwahl. In 1862 the Raja was granted a sanad allowing adoption and in 1865 local rule was reestablished. Nagod State was a part of Baghelkhand Agency from 1871 till 1931, when it was transferred along with other smaller states back to Bundelkhand Agency. The last Raja of Nagod, HH Shrimant Mahendra Singh, signed the accession of his state to the Indian Union on 1 January 1950.
