The Sanday Light Railway was a privately owned ridable miniature railway situated in Braeswick, on the island of Sanday, Orkney, Scotland.

It was the most northerly passenger carrying railway in the British Isles, and although it was primarily the owner's hobby it did achieve the status of a tourist attraction and local curiosity.

The railway also owned a number of items of rolling stock, including a very rare Cromar White first-class carriage.

[1] Although trains had been operating occasionally in some form beforehand,[2] the railway was officially opened to the public in August 2006 by Sir Peter Maxwell Davies[citation needed] just a few months before its closure, which was variously attributed to the owner being unable to keep his promise to hold Sir Peter's civil partnership ceremony there [3] or unreasonable demands placed upon the railway's operators by local council officials.

In 2008, the owner was taking legal action against a number of organisations[4] over perceived discrimination and misconduct by those organisations in relation to the railway, its associated tea-rooms and the abortive civil partnership ceremony.
