It is specified as “Made in England” on the label, but actually is from Donegal, Ireland.

From official page:

This is tweed yarn taken from carded wool. This is a traditional tweed thread from the Donegal area in Ireland. The thread and nep are all made from wool. Due to its great affinity and moderate stretch, this medium thread is easy to knit with. This will show off a classical and traditional flavor in pieces like sweaters.
