Teatro Comunale Carlo Gesualdo, Municipal theater in Avellino, Italy.

The Carlo Gesualdo Theater is a modern performing arts venue in Avellino with an oval-shaped interior auditorium and rectangular exterior footprint. It contains 12 side boxes, 5 rear boxes, and a sizable stage designed to accommodate diverse productions.

A theatre named after Carlo Gesualdo was first planned in the early 1800s under intendant Giacomo Mazas, but the project never fully took off; the building was sold in 1925 and demolished in the 1930s, replaced by Palazzo Sarchiola. The present theatre was conceived after the 23 November 1980 earthquake, designed by Carlo Aymonino and Gianmichele Aurigemma, built from 1992 to 2001, and inaugurated in 2002 with Mozart's Le nozze di Figaro.

The theatre is named after Carlo Gesualdo (1566–1613), a late-16th-century madrigalist and Prince of Venosa who lived in Irpinia, in the municipality of Gesualdo. Its seasons have featured Italian actors such as Gigi Proietti, Massimo Ranieri and Michele Placido, and for several years the venue has hosted recordings of the television programme Italia's Got Talent.

The venue seats approximately 1200 people and offers ample stage space for different types of performances. It is advisable to arrive early to explore the building's architecture and layout before your event begins.

The theatre hosts the three-year degree course in Dance Disciplines – Choreography of the Accademia Nazionale di Danza, at the time the only course of its kind in Italy. The stage is 30 metres wide and 17 metres deep, with a proscenium arch 16 metres wide and 8 metres high.
