A cyclorama is a panoramic painting on the inside of a cylindrical platform, designed to provide a viewer standing in the middle of the cylinder with a 360° view of the painting. The intended effect is to make a viewer, surrounded by the panoramic image, feel as if they were standing in the midst of an historic event or famous place.

"Cyclorama" can also refer to the building designed to show the panoramic painting (pictured).

Panoramas were invented by Irish painter Robert Barker, who wanted to find a way to capture the panoramic view from Calton Hill in central Edinburgh, Scotland. He subsequently opened his first cyclorama building in Edinburgh in 1787.

Cycloramas were very popular in the late 19th century. The most popular traveled from city to city to provide local entertainment — much like a modern movie. As the viewers stood in the center of the painting, there would often be music and a narrator telling the story of the event depicted. Sometimes dioramas were constructed in the foreground to provide additional realism to the cyclorama. Circular and hexagonal-shaped buildings were constructed in almost every major US and European city to provide a viewing space for the cycloramas. For example, a 360° depiction of the land and naval battles of Vicksburg was completed and first exhibited in Paris. This work by Lucien-Pierre Sergent and Joseph Bertrand traveled to New York, Chicago and San Francisco and Tokyo. Hundreds of cycloramas were produced; however, only about thirty survive.
