The Regent Theatre is a theatre, in Ipswich, Suffolk, England. The theatre holds just over 1,700 people, making it East Anglia's largest theatre.
Since its opening in 1929, it has also been known under two other names, the Gaumont and, for one year only, the Odeon.
It is currently run by Ipswich Borough Council, who took it on following controversy over its future in 1989.
