Langdon was named for R.B. Langdon of Langdon & Shepard, a Canadian Pacific Railway subcontracting firm who built a section of the line just east of Calgary. He was born in Vermont in 1826 and worked on the railroad lines within at least ten US states, notably the St. Paul & Pacific Railroad in 1858. Langdon served as a state senator in Minnesota from 1873 to 1881. The nearby Shepard station was named for his partner. Langdon was one of two people to turn the first sod in the settlement in 1882. A year later, a railway station was set up in a boxcar and named after him.
A post office was established on January 1, 1890, and a telegraph office in 1899. Langdon incorporated as a village on August 31, 1907. It subsequently dissolved on January 1, 1946, to become part of the Municipal District of Conrich No. 44.
As a population centre in the 2016 Census of Population conducted by Statistics Canada, Langdon recorded a population of 5,060 living in 1,582 of its 1,586 total private dwellings, a change of 20.2% from its 2011 population of 4,211.
