Nelidovo was founded in 1898 near a railway station of the same name on the private
Moscow-
Vindava-
Rybinsk Railway, from Moscow's
Rizhsky railway station. It belonged to
Belsky Uyezd of
Smolensk Governorate. On 12 July 1929, governorates and
uyezds were abolished, and Nelidovsky District with the administrative center in the settlement of Nelidovo was established. It belonged to
Rzhev Okrug of
Western Oblast. On August 1, 1930, the okrugs were abolished, and the districts were subordinated directly to the oblast. On 29 January 1935
Kalinin Oblast was established, and Nelidovsky District was transferred to Kalinin Oblast. During World War II, in 1941–1942, Nelidovo was occupied by German troops. On August 22, 1944, the district was transferred to newly established
Velikiye Luki Oblast. Nelidovo was granted town status in 1949. On October 2, 1957, Velikiye Luki Oblast was abolished, and Nelidovsky District was transferred back to Kalinin Oblast. In 1990, Kalinin Oblast was renamed Tver Oblast. ==Administrative and municipal status==
