The 2014 United SportsCar Championship (known for sponsorship reasons as the 2014 Tudor United SportsCar Championship) was the inaugural season of the International Motor Sports Association's new series created out of a merger of the Rolex Sports Car Series and the American Le Mans Series and the first to be held under the name as the United SportsCar Championship. It began with the 24 Hours of Daytona, the first time since the 1997 IMSA GT Championship season that IMSA sanctioned an event at Daytona International Speedway on 25 January and ended on 4 October at Petit Le Mans. It was the 44th overall season of IMSA GT championship racing tracing its lineage to the 1971 IMSA GT Championship.
