The Jupiter-C was an American research and development vehicle developed from the Jupiter-A. Jupiter-C was used for three uncrewed sub-orbital spaceflights in 1956 and 1957 to test re-entry nosecones that were later to be deployed on the more advanced PGM-19 Jupiter mobile missile. The recovered nosecone was displayed in the Oval Office as part of President Dwight D. Eisenhower's televised speech on November 7, 1957.

A member of the Redstone rocket family, Jupiter-C was designed by the U.S. Army Ballistic Missile Agency (ABMA), under the direction of Wernher von Braun. Three Jupiter-C flights were made. These were followed by satellite launches with the vehicle designated as Juno I (see Juno I below or the Juno I article). All were launched from Cape Canaveral, Florida.
