Sandwell Valley is an area of green belt in the West Midlands of England, on the border of Birmingham and West Bromwich, with Walsall at its northern end.

It is a valley on the River Tame, and is mostly made up of RSPB Sandwell Valley nature reserve and Sandwell Valley Country Park, with a couple of golf courses and some private fields, plus Forge Mill Farm and Sandwell Park Farm, both of which are operated by Sandwell Metropolitan Borough Council as educational facilities - the former using modern farming techniques, the latter with a walled garden and rare breeds of farm animals.

The M5 motorway bisects the valley, with the intersection between it and the M6 at the northern end.

The Birmingham-Walsall railway line, part of the old Grand Junction Railway, also uses the valley.

Historically, the valley was centered around Sandwell Priory.
