The Silver Stream (Māori: Whakaehu) (sometimes written Silverstream) is a small river flowing close to the town of Mosgiel in Otago, New Zealand.

[2] The Silver Stream rises in the Silverpeaks hills north of Dunedin, on the southern slope of Silver Peak itself, and flows initially southwards through a steep-sided forested valley which widens to become Whare Flat, before turning west at the eastern edge of the Taieri Plains at the foot of Three Mile Hill, close to Invermay Research Station.

It continues in a southwesterly direction past the northern edge of Mosgiel, reaching the Taieri River two kilometres north of Allanton.

The race began at a weir high on the river and traversed the sides of Swampy Summit and Flagstaff before emptying into a reservoir in Kaikorai Valley.

Several walking routes are located close to or in the valley of the Silver Stream, most of which are aimed at more experienced trampers.
