With a couple of exceptions, there are no denominational tartans, as far as I know. There is a tartan for one of the Episcopalian/Anglican denominations (rare and presumably quite expensive), and 2 tartans that were recently introduced by Samye Ling, a Buddhist monastery in the borders of southern Scotland.

There is a tartan for clergy, said to be the only occupational tartan, and it has several variations. Usually it is dark blue with black and white (ancient, modern, weathered, etc) but also has green and purple variations. One is black and white. However, it is said to be for all clergy, rather than any specific denomination.
