Kathyrn is a hamlet in southern Alberta under the jurisdiction of Rocky View County.

A Canadian National Railway line runs northeast through Kathyrn towards Three Hills.

Neil McKay, a local farmer and large landowner, named this hamlet after his daughter.

He had offered some of his land to the Grand Trunk Pacific Railway Company in 1911 for a townsite, on the provision that he be permitted to give it a name.

When the station was finally built in 1913, the painter who was in charge of the sign misspelled Kathryn and the settlement became known as Kathyrn.
