Electric Daisy Carnival, commonly known as EDC, is an electronic dance music festival organized by promoter and distributor Insomniac. The annual flagship event, EDC Las Vegas, is held in May at the Las Vegas Motor Speedway, and is the largest electronic dance music festival in North America with over 500,000 visitors in 2024.

The event incorporates a variety of electronic music producers and DJs, which are spread across nine stages and roaming art cars; traditionally, the Las Vegas edition has operated under a dusk-to-dawn schedule, with lineups beginning in the late-evening, and concluding at sunrise the following morning on each day. The festival grounds also include various art installations and other attractions, including carnival entertainers and amusement rides.

Since its inception, other EDC events have been held in other states and abroad, including Mexico, Puerto Rico, the UK, Brazil, Japan and India. As of 2026, EDC is held annually in Las Vegas and Orlando, along with international editions in China, Colombia, Mexico, South Korea, and Thailand.

In 2009, EDC became a two-day event, and in 2011, a three-day event. In 2024, it had a total attendance of 525,000 over three days. In 2027, the festival will expand to two weekends. In 2018, EDC Las Vegas expanded the festival to include an on-site camping experience. The festival has eight stages, each catering to different genres of EDM, with the largest, Kinetic Field, being able to accommodate 70,000. It also has 18 carnival rides, four Ferris wheels, and a staff of more than 5,000 people. In 2019, access to purchasing tickets to EDC was expanded to mobile phone apps for convenience. In 2017, EDC won the Festival of the Year award at the Electronic Music Awards.

The Electric Daisy Carnival had its roots in 1986, when Stephen Hauptfuhr first started throwing underground parties. He organised the first Electric Daisy Carnival in 1991 in Chino, California. It had an outdoor carnival and drew 3,000 to 3,500 people who were impressed by the carnival atmosphere. He subsequently organised the 1992 and 1995 editions as well.

Philip Blaine—Pasquale's partner—made the deal to grant use of the name Electric Daisy Carnival in 1995 to Pasqualle Rotella CEO of Insomniac Events. Between 1995 and EDC, Philip and Pasquale created the now legendary Organic '96 event.

Insomniac debuted their signature event, Electric Daisy Carnival, in 1997 at the Shrine Expo Hall in Los Angeles, California.

In 1999, Electric Daisy Carnival took place at Lake Dolores Waterpark in Newberry Springs, California.^{[citation needed]}
