Silver Stream Railway is a heritage railway at Silverstream in the Hutt Valley near Wellington, New Zealand. It regularly operates preserved New Zealand Railways Department locomotives along a restored section of the Hutt Valley Line before a deviation was built in 1954.

Silverstream is a suburb of Upper Hutt in New Zealand, just under 7 km south-west of the Upper Hutt CBD. It is in the lower (southern) part of the North Island of New Zealand at the southern end of Upper Hutt, close to the Taitā Gorge, which separates Upper Hutt from Lower Hutt. The area is sited at the mouth of a small valley formed by the Wellington Region's tectonic activity and, in part, by Hull's Creek, which discharges into the Hutt River.
