Tuni is a closed railway station in Adelaide, South Australia. It was located in what is now the western outskirts of the town of McLaren Vale.
It was a ground level stopping place during the passenger transport days of this line, and a 1965 reference mentioned that it was no longer used at that date.
The stop is now completely disused, the entire Willunga railway line having been dismantled in 1972, and now provides the route for the Coast to Vines Rail Trail.
