Teatro Peón Contreras, Opera house in Mérida, Mexico.

Teatro Peón Contreras is a two-storey theatre on Calle 57 in central Mérida, with a pale yellow facade, rusticated ground floor and tall upper windows between pilasters. Inside, a marble staircase leads to a hall ringed by five tiers of boxes and a 700–750-seat capacity. A dome painted with Greek muses crowns the auditorium.

The present building was constructed from 1900 to 1908 to a design by the Italian architect Pío Pialentini, with the Italian contractor Enrico Deserti; it opened on 21 December 1908 with a charity musical evening. It replaced two earlier theatres on the same site, San Carlos (1806) and Bolio (1878), and took its current name on 27 December 1878. In early 1916 it hosted Mexico's first Feminist Congress.

The theater serves as home to the Yucatán Symphony Orchestra and regularly hosts operas, dance performances, and theatrical productions. It remains central to the city's cultural life, attracting artists and audiences from across the region.

The theatre stands on Calle 57 in Mérida's centre, with the entrance set back behind a large tree on the facade. Inside, a marble staircase leads from the lobby up to the main hall and the galleries on the upper floor. The hall is ringed by tiers of boxes, so seats on the upper levels are reached by stairs.

The dome above the auditorium is decorated with paintings of Greek muses, a detail easy to miss from the seats below. The building was planned by the Italian architect Pío Pialentini and built by the contractor Enrico Deserti from 1900; the theatre opened on 21 December 1908.
