The One Per Desk, or OPD, was a British innovative hybrid personal computer and telecommunications terminal based on the hardware of the Sinclair QL. The One Per Desk was built by International Computers Limited (ICL) and launched in the United Kingdom in 1984. It was designed to run business-related software packages, not as a general-purpose computer.

Rebadged versions of the OPD were sold in the UK by British Telecom as the Merlin Tonto, and as the Computerphone by Telecom Australia and the New Zealand Post Office.
