DECpc was a wide-ranging family of desktop computers, laptops, servers, and workstations sold by Digital Equipment Corporation. The vast majority in the family are based on x86 processors, although the AXP 150 uses DEC's own Alpha processor.

The line was DEC's attempt to finally succeed in selling IBM PC compatibles; even its existing customers were buying PCs from Compaq and Hewlett-Packard. The company said that while "the Digital of yesterday was not known for competitive prices, this new line of PC offerings is competitive in features and price". Some entries in the desktop DECpc range were built by Olivetti S.p.A. and Tandy Corporation.
