Strathtay Scottish was a bus operator running services in Dundee, Angus and parts of Grampian in eastern Scotland.

The company would have a turbulent infancy, facing very heavy competition from Perth-based operator Stagecoach, who engaged in a bus war with Strathtay Scottish between 1989 and 1991.

After managing director Neil Renilson had resigned from Strathtay Scottish to join Stagecoach ahead of the company's commencement of Perth services on 19 June 1989,[2][3] Strathtay Scottish purchased a number of ex-London Transport AEC Routemaster buses to compete with Stagecoach,[4] which also used a number of the same vehicle type on city services in Perth.

A new Perth City Transport brand was created by Strathtay Scottish to compete with Stagecoach, with buses painted in a red and white livery.

As Stagecoach grew nationally, it became financially stronger and had ready access to vehicles from the larger companies in England it had purchased; Strathtay Scottish, meanwhile, was ultimately unable to sustain the level of intense competition that ensued.
