Ogden Water is a water supply reservoir at the top of the Hebble Valley between Halifax and Keighley in West Yorkshire (there is also a reservoir of the same name in Lancashire).

Ogden was Halifax Corporation Water Works’ first impounding reservoir. Completed in 1858 under engineer John Frederick Bateman, the reservoir is fed by Ogden Clough and Skirden Clough. It is approximately 19m deep with a surface area of about 14ha and a capacity of just over a million cubic metres.

The reservoir itself is owned by Yorkshire Water but the catchment area, comprising managed woodland and moorland, is designated as a nature reserve and managed by Calderdale Council as a public amenity, with a network of paths and orienteering trails.
