The Letterkenny Shopping Centre is a shopping centre in Letterkenny, Ireland. Built in 1984, it is the largest shopping centre in County Donegal, and was the first of several such complexes in Letterkenny. It is also the third largest in the Harcourt Developments retail portfolio. While originally built on the outskirts of the town, urban expansion means it now lies in the town proper. Letterkenny has been identified as one of Europe's fastest growing towns by business owners.
The main anchor stores have been Quinnsworth (now Tesco) and Penneys department store. The shopping centre comprises 11,705 m² of retail space and over 40 retail units.
The centre remained largely unchanged until 2004, when the centre was expanded , and new lighting, flooring and decor were added. More retail units were constructed along with the expansion of the Tesco outlet and thus becoming "one of the Major developments in Ireland". The carpark was extended to allow for a capacity of 750. The entire project was overseen by the Burke Morrison Engineering firm.
