The '''PDP-7''' is an [[18-bit computing|18-bit]] [[minicomputer]] produced by [[Digital Equipment Corporation]] as part of the [[Programmed Data Processor|PDP]] series.

The PDP-7 is the third of Digital's 18-bit machines, with essentially the same [[instruction set architecture]] as the [[PDP-4]] and the [[PDP-9]].
