WPEI (95.9 FM) is a WEEI Sports Radio Network station serving the Portland, Maine, area.

On August 31, 2008, at 6 p.m., WRED dropped its rhythmic top 40 format after a farewell from station DJs (airstaff and listeners had been notified a week in advance).

WRED and WJJB-FM (which was simulcasting The Big JAB) then flipped to programming provided by Boston's WEEI, with the simulcast of The Big JAB moving to 96.3 FM.

WPEI carries ESPN Radio when not airing WEEI; it had previously carried Fox Sports Radio (now on The Big JAB) and Sporting News Radio (simulcast from The Big JAB, before WZAN dropped the FSR affiliation).

WPEI has been the flagship station of the Portland Sea Dogs since 2012, taking over for WBAE/WVAE that year.
