The M90 is a major motorway in Scotland. It runs from Junction 1A of the M9 motorway, south of the Queensferry Crossing, to Perth. It is the northernmost motorway in the United Kingdom.

The northern point of the motorway splits into two between the Broxden Roundabout (Leading to Perth and the A9 towards Inverness and Thurso) and the A90 towards Dundee and Aberdeen. The southern point leads into the M9 towards Stirling and the M8 towards Edinburgh and Glasgow.

A small part of the M90 (across the Friarton Bridge to the southeast of Perth) was originally numbered as the M85 motorway.
