The Anaheim Convention Center is a major convention center in Anaheim, California, and is the largest exhibition facility on the West Coast of the United States. It is located across from the Disneyland Resort on Katella Avenue. The original components, designed by Adrian Wilson & Associates and built by the Del E. Webb Corporation, opened in July 1967—including a basketball arena followed shortly by the convention hall. It holds many events, like Star Wars Celebration, VidCon, BlizzCon, Anime Expo, D23 Expo, WonderCon, NAMM Show, Pokémon World Championships, competitions, and more. In addition to hosting various types of conventions, the Anaheim Convention Center was used to host the wrestling during the 1984 Summer Olympics.

The center has subsequently undergone six major expansions (1974, 1982, 1990, 1993, 1999–2000, 2016–2017). It is the largest exhibit facility on the West Coast.

Originally, the arena was home to the Anaheim Amigos of the American Basketball Association during the first ABA season, 1967–68. The franchise relocated to the Los Angeles Sports Arena and became the Los Angeles Stars immediately thereafter; the team eventually moved to Salt Lake City and became the Utah Stars, capturing the 1970–71 ABA Championship. The Stars' subsequent fan support in Utah set the foundation for the NBA's Utah Jazz. The San Diego Friars of WTT played some of their home matches in the arena between 1975 and 1977. In 1978, the Anaheim Oranges of WTT used the arena as their primary home venue. The arena was also home to the California Surf of the NASL for one indoor season (1979–80).

According to frequent news reports, the largest exposition held at the Convention Center in recent years has been the Winter NAMM Show. This music-equipment convention (trade only, not open to the general public) had over 2,000 exhibitors and a record-breaking 115,888 attendees during the 2020 show. The NAMM Show has been running at the Anaheim Center since 1977, except for a three-year break in 1998–2000 while the Convention Center underwent major renovations, and in 2021 due to the COVID-19 pandemic. In 2008, news reports indicated that NAMM's long-term lease with the Anaheim Convention Center authority would end in 2010, and NAMM was applying pressure to the City of Anaheim to further expand and improve the convention center. The NAMM Show did ultimately occur in the convention center in 2011 and the subsequent years.

The Anime Expo was hosted at the Anaheim Convention Center in 1996 and again from 2003 through 2006 and was one of the convention center's biggest public events.

Blizzard Entertainment holds BlizzCon at the venue. In 2005, BlizzCon used the northern two conference halls, (and the arena for a concert one evening). In 2007 and 2008, it used three conference halls. In 2009, it used four conference halls. While tickets to the 2007 event sold out in 3 days, tickets to the October 2008 event sold out "within minutes," and tickets to the August 2009 event sold out in "56 seconds". Tickets to the 2010 Blizzcon reportedly sold out within 30 seconds.

Another large convention held at the center is the Medical Design and Manufacturing Show, held shortly after Winter NAMM.

The venue served as the site for wrestling at the 1984 Summer Olympics.
