History
Ōnuma-Kōen Station traces its origin to a temporary stop opened on 5 June 1907 by the Hokkaidō Railway, nationalised the following month and closed at year's end. It reopened as a seasonal Ministry of Communication halt in 1908, gained freight service in 1917, was renamed Ōnuma in 1920, and was promoted to a full station on 10 November 1924. Freight handling ceased on 20 May 1960. The current name was restored on 1 May 1964, after the neighbouring stop reclaimed the plain Ōnuma title. The wooden depot was rebuilt in March 1983, and on 1 April 1987 the JNR split transferred operation to JR Hokkaido.

Notes
Since 2015 the station has played the song Sen no Kaze ni Natte as a train-arrival melody, marking the chime point on the Hokuto express stop list.
