Neidpath was first settled in 1909 but was officially founded in the 1920s with the construction of the railroad. It was named after Neidpath Castle in Scotland. The population peaked before 1930 when it reached about 100 people. It then began to decline and later a fire destroyed the general store and then the school was closed. The last operating businesses in town were the grain elevators, of which there used to be four, but there are only two left today. In 2014, Neidpath had a population of 1 but it now has 0.
