控制数据公司（英语：Control Data Corporation，CDC），又译为康大信息公司，创建于1957年，是超级电脑的先驱。在1960年代，它是极为有名的公司。在1980年代，因为连串的决策失误，于1988年，他们决定卖掉公司大部份资产，离开了电脑制造的行业，在1992年，清算完成，重建为控制数据系统公司（Control Data Systems, Inc.）。原有CDC公司的业务，交由Ceridian继续营运。

Control Data Corporation (CDC) was a supercomputer firm. CDC was one of the nine major United States computer companies through most of the 1960s; the others were IBM, Burroughs Corporation, DEC, NCR, General Electric, Honeywell, RCA, and UNIVAC. CDC was well-known and highly regarded throughout the industry at the time. For most of the 1960s, Seymour Cray worked at CDC and developed a series of machines that were the fastest computers in the world by far, until Cray left the company to found Cray Research (CRI) in the 1970s. After several years of losses in the early 1980s, in 1988 CDC started to leave the computer manufacturing business and sell the related parts of the company, a process that was completed in 1992 with the creation of Control Data Systems, Inc. The remaining businesses of CDC currently operate as Ceridian.
