The Knebworth and Winter Green Railway was a {{RailGauge|1ft11.5in|lk=on}} narrow gauge railway built in the grounds of Knebworth House in 1972 as a tourist attraction.

The railway was built by Pleasurerail Ltd. a company set up to build and operate private tourist railways which included the Great Whipsnade Railway and also the line at Blenheim Palace. In 1971, they started construction on a railway in the grounds of Knebworth House near Stevenage.{{cite book |title=On the British Narrow Gauge |first=Michael |last=Harris |publisher=Amberley Publishing Limited |date=15 November 2019}} The initial line was an end-to-end layout running from the house to the adventure playground. In 1980, the track was extended to form a mile-long continuous loop.

During its existence, the line hosted a number of steam and diesel locomotives. The line continued to run until 1990 when it was lifted and the remaining stock transferred to other lines
