Irma board, originally spelled IRMA board, refers to a brand of coaxial interface cards for PCs and Macintosh computers used to enable 3270 emulator programs to connect to IBM mainframe computers.

IRMA boards were made from 1982 on by Digital Communications Associates, Inc. (DCA) of Alpharetta, Georgia, who in 1994 merged into Attachmate Corporation of Bellevue, Washington.
