The A823(M) is a motorway in Fife, Scotland.

It is a 1-mile-long (1.6 km) 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[2] it was intended to be part of a longer motorway continuing eastbound along to the north coast of the Firth of Forth[3] and a bridge was built for this extension.

Following the upgrade of the A92 it is unlikely this route will be constructed.
