Dale Arnold (born March 27, 1956) is a sportscaster who is primarily known as the co-host of the Dale & Holley Show on WEEI and the former play-by-play announcer for the Boston Bruins.

A Bowdoin College alum, Arnold began calling games for the school teams while a student there in the mid-1970's. In 1979, he succeeded Mike Emrick as the voice of the Maine Mariners. He joined the New Jersey Devils as their radio announcer in 1986, before returning to New England two years later. Arnold called New England Patriots games from 1988-90, and provided play-by-play coverage for Bruins home games from 1995-2007. 

Arnold currently hosts a midday talk show, Dale & Holley, with former Boston Globe columnist Michael Holley on Sportsradio 850 WEEI in Boston from 10 AM to 2 PM. Arnold has been with the radio station since its inception in 1993, and has been a constant in the midday time slot for several years. 

On February 11, 2008, Entercom and the Boston Red Sox announced that Arnold would be part of the four person Red Sox Radio broadcast team for the 2008 season. For the 2008 season, Arnold or Jon Rish will fill in to cover games with Joe Castiglione when Dave O'Brien is honoring his ESPN duties. Rish and Arnold will be filling the part time role held by Glenn Geffner during the 2007 season.

Dale is the only sportscaster to do the play-by-pay for ALL FIVE major sports teams in New England (Red Sox, Patriots, Celtics, Bruins and Revolution).

Arnold, a two-time Emmy Award winner, and his wife Susan, have three children, Taylor, Alysha, and Brianna.
