Trafalgar Studios is a West End theatre near Trafalgar Square in London. Originally named the Whitehall Theatre, the building was designed by architects Tim Foster and John Muir. It is home to two spaces: Studio 1 and Studio 2. They are both intimate venues with 380 and 100-seat capacities respectively.

The current building was constructed on the site of a 17th century inn called Ye Old Ship Tavern. It opened in 1930, and produced several plays in its early years. During the Second World War, the venue hosted cabaret-style evenings which featured different kinds of entertainment. In 1942, the theatre began hosting Phyllis Dixey, who performed the first striptease show to appear in the West End. She performed at the theatre for the next five years.

The theatre continued to produce revue shows into the late 1960s but after a fall in popularity, the venue closed down for over ten years. It underwent major refurbishment in this time, but retained its Art Deco features. During the 1980s and 1990s, the theatre returned to presenting theatrical productions, but also doubled up as a television and radio studio hosting shows such as Live From London. Fast forward to current years, and this Grade II listed building continues to host a variety of critically acclaimed plays and musicals.
