Arena Birmingham (known as Utilita Arena Birmingham, and previously as The Barclaycard Arena and originally as the National Indoor Arena) is an indoor arena and sporting venue in central Birmingham, United Kingdom. It is owned by parent company the NEC Group. When it was opened in 1991, it was the largest indoor arena in the UK.

The arena is located alongside the Birmingham Canal Navigations Main Line's Old Turn Junction and opposite the National Sea Life Centre in Brindleyplace. The building straddles the main Birmingham to Wolverhampton Intercity railway line (originally the Stour Valley Line), but does not have a station of its own.
