Loudwater railway station was a railway station which served Loudwater, Buckinghamshire and Flackwell Heath, on the Wycombe Railway.

Loudwater station was located at the bottom of Treadaway Hill close to the M40 bridge and served both Loudwater and Flackwell Heath.

It opened in 1854 and the station became a halt in 1968 because of decreased service on the line.

[2] The site is now an industrial park, although at the rear of the park the old railway tunnel under the M40 is still in place.

The station appears briefly in an early scene of The Reptile (1966) made by Hammer Film Productions.
