木星-C探空火箭是一种探空火箭，又称为丘比特-C型火箭或是天帝-C，曾用于1956年及1957年间3次亚轨道飞行任务中。

The Jupiter-C was an American Research and development vehicle developed from the Jupiter-A. Jupiter-C was used for three 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. 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 followed by three satellite launches (Juno I). All were launched from Cape Canaveral, Florida.
