Okuōikojō Station (奥大井湖上駅, Okuōikojō-eki) is a train station in Kawanehon, Haibara District, Shizuoka Prefecture, Japan, operated by the Ōigawa Railway.

Okuōikojō Station is served by the Ikawa Line, and is located 13.9 kilometers from the official starting point of the line at Senzu.

The station has one side platforms serving a single track, with a small shelter on the platform for passengers. The station is unattended.

Okuōikojō Station was opened on October 2, 1990, when part of the Ikawa Line was re-routed to avoid the rising waters of the lake created by the Nagashima Dam. Located on a cliff next to the Okuōi Reservoir created by the Nagashima Dam, the station platform partially extends onto a bridge spanning the reservoir.

In fiscal 2017, the station was used by an average of 16 passengers daily (boarding passengers only).
