St Gall Gardens South is a residential area in the suburb of Milltown in Dublin, Ireland. It is located in the D14 postal district. There is not much of interest on the street except for a Marian Grotto at one end and the green postbox.

As a matter of interest St Gall is the name of a wheel shaped hard cheese made from the milk of Friesian cows, which won a Gold Medal at the World Cheese Awards held in Dublin 2008.

Gall (Latin: Gallus; c. 550 – c. 646) according to hagiographic tradition was a disciple and one of the traditional twelve companions of Columbanus on his mission from Ireland to the continent. However, he may have originally come from the border region between Lorraine and Alemannia and only met Columbanus at the monastery of Luxeuil in the Vosges. Gall is known as a representative of the Irish monastic tradition. The Abbey of Saint Gall in the city of Saint Gallen, Switzerland was built upon his original hermitage. Deicolus was the elder brother of Gall.
