数字研究公司（Digital Research Inc.），简称DR或DRI，是一家以为迷你电脑“PDP-11”编写操作系统而起家的电脑公司，总部位于美国加州蒙特雷县太平洋丛林市（Pacific Grove），1974年创立，1991年被Novell公司收购。及至Linux兴起，又从Novell分拆出来，成为Caltech。现在由DeviceLogics拥有。

很多人都将数字研究公司和迪吉多（Digital Equipment Corporation；DEC）混淆，其实两家公司完全没有关系。

Digital Research, Inc. (a.k.a. DR or DRI; originally Intergalactic Digital Research) was the company created by Dr. Gary Kildall to market and develop his CP/M operating system and related products. It was the first large software company in the microcomputer world. Digital Research was based in Pacific Grove, California.
