Morley and Rothwell was a parliamentary constituency represented in the House of Commons of the Parliament of the United Kingdom.

It was held for the entire period of its existence by the Labour Party.

The constituency covered the West Yorkshire towns of Morley and Rothwell, the villages that surround the towns, and the old pit village of Middleton.

Following their review of parliamentary representation in West Yorkshire, the Boundary Commission for England created a number of modified constituencies as a consequence of a falling population.

Middleton was transferred to the Leeds Central seat.
