The Richard J. Codey Arena at South Mountain (formerly the South Mountain Arena) is an ice hockey and ice skating arena in West Orange as part of the South Mountain Recreation Complex. The arena is named for former Governor of New Jersey Richard Codey. The facility is owned and operated by the Essex County Department of Parks, Recreation and Cultural Affairs.

South Mountain Arena originally opened in 1958, with the second, smaller rink added in 1983. During 2004 and 2005 the arena underwent major renovations that included a new state-of-the-art lobby for the arena, including meeting rooms, a skylight, automatic doors, pro shop (now a glice training area), arcade, and concession stand. Another part of the renovation was a new set of dasher boards, Plexiglas, compression system, jumbo-tron screen, and seats for Rink 1, as well as a new dehumidifier for Rink 2; it was renamed the Codey Arena upon reopening.

The arena has two NHL-sized skating rinks. The main arena has a seating capacity of 2,500 and the second rink seats approximately 500. Codey Arena is home to Seton Hall Prep's hockey program and has also hosted the Prep's graduation ceremony several times.
