Cassiobridge was a proposed London Underground station in Watford, Hertfordshire, England. The station would have been part of the Croxley Rail Link project, a scheme to extend the Metropolitan line to Watford Junction railway station. It would have been served by Metropolitan line trains between Watford Junction and Central London via Baker Street. The railway line would run over Ascot Road via a viaduct and the platforms would have been situated on the east side of the road. Entrance to the station would have been from the west side of the road, with a ticket hall and other facilities at street level. Passengers would gain access to the platforms via stairs and lifts and a short footbridge over the road.

The Croxley Rail Link, or the Metropolitan Line Extension, is a proposed railway engineering project in the Watford and Three Rivers districts of Hertfordshire, England, that would have connected the London Overground and the London Underground's Metropolitan line at Watford Junction. If the link were to go ahead, the Metropolitan line's terminus at Watford Underground station would be closed and the line diverted and extended from Croxley to Watford Junction via a reopened section of closed line. The main proponent of the scheme has been Hertfordshire County Council but it failed to win the support of Transport for London (TfL) which owns the Watford branch. The engineering works would have consisted of the realignment of the disused Watford and Rickmansworth Railway's line between Croxley Green and Watford High Street, with the construction of a viaduct over the Grand Union Canal, River Gade and A412 road and two new stations before branching into the London Overground line near Watford High Street and continuing to Watford Junction.

Originally the station was to be named either Watford Hospital or Watford General Hospital. On 25 January 2017, the Watford Observer newspaper published an update on the Croxley Rail Link confirming work had stopped as there was an ongoing funding issue.
