The A823(M) is a motorway in Fife, Scotland. It is a 1 mi spur from the M90 into Dunfermline. The road provides a fast route for traffic from Dunfermline to the Forth Road Bridge. When it opened in 1964 it was intended to be part of a longer motorway continuing eastbound along to the north coast of the Firth of Forth and a bridge was built for this extension. Following the upgrade of the A92 it is unlikely this route will be constructed.
