Sunnynook busway station is the smallest station on the Northern Busway in Auckland, New Zealand. It is located in the suburb of Sunnynook. Many passengers walk to the station, one of the busiest on the busway, as it does not have park and ride facilities like the other busway stations.

The Northern Busway is a segregated busway that runs along the eastern side of the Northern Motorway, part of State Highway 1, in the north of Auckland, New Zealand, linking the North Shore with the northern end of the Auckland Harbour Bridge. As of May 2022, the busway consists of two-way lanes running between Albany Station and Akoranga Station, and from Akoranga Station a southbound-only lane that joins the harbour bridge approaches just south of the Onewa Road on-ramp system. The busway previously ended at Constellation before an extension to Albany was constructed in 2022.
