Bradbury Science Museum, Technology museum in Los Alamos, United States.

The Bradbury Science Museum is a technology museum in downtown Los Alamos, New Mexico, focused on the work of the Los Alamos National Laboratory. The galleries cover topics such as nuclear physics, supercomputing, and space research through hands-on exhibits.

Robert Krohn proposed a museum in 1953 to hold relics of the laboratory's weapons research, and an old ice house on Ashley Pond, already fitted with a vault door, opened to official visitors in 1954. Unclassified exhibits moved to public view in 1963, drawing 14,000 visitors from 50 states and 40 countries in the first year. The museum was renamed for Norris E. Bradbury in 1970 and moved to its present downtown building in April 1993.

The museum's name honours Norris E. Bradbury, the laboratory's second director from 1945 to 1970; it was renamed for him in 1970. The Little Boy and Fat Man bombs are shown as full-size models, not originals. A 20-minute film on the Manhattan Project runs in the galleries, and admission is free.

The museum sits in the center of Los Alamos and is easy to reach on foot from the town's main square. Admission is free, and the exhibits are accessible for visitors of all ages.

The museum displays full-scale replicas of the Little Boy and Fat Man bombs dropped in 1945, giving a rare look at how these weapons were built. These objects are among the few publicly accessible physical representations of their kind in the world.
