Spennells Valley is a local nature reserve in south-east Kidderminster, in Worcestershire, England.

It was declared a local nature reserve (LNR) in 1995, and is owned and managed by Wyre Forest District Council.

[1] The reserve, area 15.7 hectares (39 acres), is situated along the banks of Hoo Brook.

It is a link between Wilden Marsh (a nature reserve of Worcestershire Wildlife Trust[2]) to the south-west and the upper Hoo Brook pools to the north-east.

It involves the creation of new ponds; it is expected that the project (underway in 2020), which is run in conjunction with the Environment Agency, will increase the biodiversity of the area of Hoo Brook.
