Ōishida Station opened on 21 October 1901 as the terminus reached when the government-owned Ou Southern Line was extended north from Tateoka Station (now Murayama Station), in what is now Ōishida, Kitamurayama District, Yamagata Prefecture. It became an intermediate station when the line was extended to Funagata on 21 July 1902, and was reclassified to the Ou Main Line on 12 October 1909. On 4 December 1999 the Yamagata Shinkansen was extended to Shinjō, making Ōishida a Yamagata Shinkansen stop. It is operated today by JR East. Ōishida is the sole municipality in Kitamurayama District, a town of roughly 6,000 along the Mogami River. Historically it prospered as the largest goods-transhipment hub on the Mogami River: the three rapids of Goten, Hayabusa and Mikagase, upstream to the south, meant that large river boats coming up from Sakata Port could get no further, so cargo had to be unloaded at Ōishida River Port and either re-loaded onto smaller boats or carried overland around the rapids — a logistic role that extended the town's commercial reach over the Ou Mountains into Sendai Domain.

Ōishida was a tenryō (shogunate-direct territory) and hosted the Ōishida Boat Office (大石田川船役所) for Mogami River shipping administration; meanwhile across the river the Yokoyama and Tazawa districts were an exclave of Shinjō Domain that maintained the Yokoyama Bansho checkpoint throughout the Edo period.
