A mitre or miter joint is a joint made by beveling each of two parts to be joined, usually at a 45° angle, to form a corner, usually a 90° angle. It is often used in making picture frames.

In woodwork, it is one way of joining two pieces of moulding that meet at an angle. (Compare the cope cut.)

It is also done in pipe work, to take ducts around a corner, or in pipe organs, to fit a large bass pipe into a small space.(The same cut is used to shape of the resonators of certain reed ranks—e.g. see [http://www.ashtonorgan.wanadoo.co.uk/ashton_organ/about/images/great_ranks.jpg Great ranks and Pedal reeds of Ashton Hall organ—but only the other kind are called "mitered pipes". And, "mitered pipes" are sometimes constructed without miter cuts.
