Aer Lingus Regional is an Aer Lingus brand used for commuter and regional flights operated by Irish airline Stobart Air on behalf of Aer Lingus. Aer Lingus Regional operates scheduled passenger services primarily from Ireland to the UK, France and the Channel Islands. Its bases are located at Cork and Dublin airports.

The possibility of such a partnership was first announced on 6 January 2010, when Aer Lingus hinted to the media that it was interested in expanding its UK services with the help of the then Aer Arann. It was also marked as solely a Cork expansion with no mention of Dublin, with Aer Lingus saying bulk seats would be bought on Aer Arann planes without an actual financial take-over.

On 26 January 2010, it was confirmed that both Aer Lingus and Aer Arann would launch a new franchise agreement. On that same date, new routes from Dublin to Doncaster-Sheffield and Durham Tees Valley were announced by Aer Lingus Regional, in addition to a new route from Cork to Glasgow. It was also decided that previous Aer Arann routes to Cork would all be transferred to Aer Lingus Regional. Aer Arann services to Blackpool and Cardiff from Dublin would be transferred to Aer Lingus Regional also.

Though Aer Arann and Aer Lingus co-founded Aer Lingus Regional, Aer Arann operate all flights and will manage those flights with Aer Arann flight crew on board. All aircraft are painted in Aer Lingus Regional livery, and both airlines anticipate new routes being announced as the new subsidiary between the two airlines grows.

On 14 March 2012, Aer Arann confirmed it would streamline all of its own branded services into Aer Lingus Regional from 25 March 2012. Routes that transferred to Aer Lingus Regional included, Dublin to the Isle of Man and Kerry, Waterford to London-Luton, London-Southend and Manchester. The airline has since suspended all services from Waterford.
