The Booth Theatre is a Broadway theater at 222 West 45th Street (George Abbott Way) in the Theater District of Midtown Manhattan in New York City, New York, U.S. Opened in 1913, the theater was designed by Henry Beaumont Herts in the Italian Renaissance style and was built for the Shubert brothers. The venue was originally operated by Winthrop Ames, who named it for 19th-century American actor Edwin Booth. It has 800 seats across two levels and is operated by The Shubert Organization. The facade and parts of the interior are New York City landmarks.

The Booth's facade is made of brick and terracotta, with sgraffito decorations designed in stucco. Three arches face north onto 45th Street, and a curved corner faces east toward Broadway. To the east, the Shubert Alley facade includes doors to the lobby and the stage house. The auditorium contains an orchestra level, one balcony, box seats, and a coved ceiling. The walls are decorated with wooden paneling with windows above, an unusual design for Broadway theaters, and there is an elliptical proscenium arch at the front of the auditorium. The stage house to the south is shared with the Shubert Theatre, and a gift shop occupies some of the former dressing rooms.

The Shubert brothers developed the Booth and Shubert theaters as their first venues on the block. It opened on October 16, 1913, with Arnold Bennett's play The Great Adventure. Ames leased the theater and showed many of his own productions until 1932, when the Shuberts took over. Many of the Booth's initial productions had short runs, particularly in the 1930s, but longer runs began to predominate by the 1940s. Long-running productions have included Luv, Butterflies Are Free, That Championship Season, For Colored Girls Who Have Considered Suicide / When the Rainbow Is Enuf, and The Elephant Man.

The Booth Theatre is on 224 West 45th Street, on the north sidewalk between Eighth Avenue and Seventh Avenue, near Times Square in the Theater District of Midtown Manhattan in New York City, New York, U.S. It shares a land lot with the Shubert Theatre directly to the south, though the theaters are separate buildings. The lot covers 25,305 square feet (2,350.9 m²), with a frontage of 126 feet (38 m) on 44th and 45th Streets and 200.83 feet (61 m) on Shubert Alley to the east. The Booth Theatre building takes up 90 feet (27 m) of the Shubert Alley frontage.

The Booth is part of the largest concentration of Broadway theaters on a single block. The adjoining block of 45th Street is also known as George Abbott Way, and foot traffic on the street increases box-office totals for the theaters there. The Booth adjoins six other theaters: the Majestic and Broadhurst to the southwest; the John Golden, Bernard B. Jacobs, and Gerald Schoenfeld to the west; and the Shubert to the south. Other nearby structures include the Row NYC Hotel to the west; the Music Box Theatre, Imperial Theatre, and Richard Rodgers Theatre to the north; One Astor Plaza to the east; 1501 Broadway to the southeast; and the Hayes Theater and St. James Theatre one block south. The Broadhurst, Schoenfeld (originally Plymouth), Booth, and Shubert theaters were all developed by the Shubert brothers between 44th and 45th Streets, occupying land previously owned by the Astor family. The Shuberts bought the land under all four theaters from the Astors in 1948.

The Shubert and Booth theaters were developed as a pair and are the oldest theaters on the block. The site was previously occupied by several houses on 44th and 45th Street. The adjacent Shubert Alley, built along with the Shubert and Booth theaters, was originally a 15-foot-wide (4.6 m) fire escape passage. Shubert Alley's presence not only allowed the theaters to meet fire regulations but also enabled the structures to be designed as corner lots. Originally, the theaters faced the Hotel Astor, now the location of One Astor Plaza, across the alley. Another private alley runs to the west, between the Booth/Shubert and Broadhurst/Schoenfeld theaters. The Broadhurst and Schoenfeld were also built as a pair, occupying land left over from the development of the Shubert and Booth; these too are designed with curved corners facing Broadway.

The Booth Theatre was designed by Henry Beaumont Herts and constructed in 1913 for the Shubert brothers. Herts was an experienced theatrical architect and had previously led the firm of Herts & Tallant, which designed such theaters as the Lyceum, the New Amsterdam, and the Liberty. The Shubert and Booth theaters are within separate buildings and differ in their interior designs and functions, although they have adjacent stage areas near the center of the block. The Shubert was the larger house, intended to be suitable for musicals, and the Shubert family's offices were placed above the auditorium there. By contrast, the Booth was intended to be smaller and more intimate. The Booth Theatre is operated by The Shubert Organization.

The facades of the two theaters are similar in arrangement, being designed in an Italian Renaissance style. The structures both have curved corners facing Broadway, since most audience members reached the theaters from that direction. The Booth's facade is made of white brick, laid in English-cross bondwork, as well as terracotta. An early source described the theaters' facades as being made of white marble, with stucco and faience panels. The main section of the theater is topped by a cornice with sheet-metal brackets designed to resemble theatrical masks. A balustrade used to run above the cornice. The western wall is plain and has a fire escape. A critic for Architecture magazine wrote that Herts had "discovered an excellent motive for a single facade", although it "would perhaps have been more amusing" if the two theaters had contained different facades.
