Space Ghost (Thaddeus Bach) is a fictional superhero created by American company Hanna-Barbera Productions in the 1960s for TV network CBS. He was designed by Alex Toth.

In the 1990s, Space Ghost was brought back as a host for his own fictional late-night talk show, Space Ghost Coast to Coast, on Cartoon Network and Adult Swim. In the 2000s, he was revamped as a serious superhero once again in a mini-series by DC Comics.
