Baraundha (also known as Pathar Kachhar) was a princely state of colonial India, located in modern Satna district of Madhya Pradesh. Although historically far larger, at the time of Indian independence in 1947, it was a petty sanad state of about 565 km2. The ruling family, members of the Raghuvansi line of Rajputs, had held the country for at least 400 years. The original seat of the family was in Rasin, in modern Banda district, originally called Raja Vasini. During the reign of the British Raj, the state commanded a privy purse of 14,500R and a hereditary gun salute of 9 guns.
The early history of the state is very obscure. The name Pathar Kachhar was derived from the country's position on the skirts of the Vindhayas. On the accession of the British to political supremacy, Thakur Mohkam Singh (1790–1827) was recognized and confirmed in his territory by a sanad granted in 1807. The last raja of Baraundha was Raja Ram Pratap Singh, who ruled from 1933, and ascended his state to the Union of India on 1 January 1950.
