Joseph Kubert (/ˈkjuːbərt/; September 18, 1926 – August 12, 2012) was a Polish-born American comic book artist, art teacher, and founder of The Kubert School. He is best known for his work on the DC Comics characters Sgt. Rock and Hawkman. He is also known for working on his creations, such as Tor, Son of Sinbad, and the Viking Prince, and, with writer Robin Moore, the comic strip Tales of the Green Beret.

Two of Kubert's sons, Andy Kubert and Adam Kubert, themselves became recognized comic book artists, as did Andy's daughter Emma Kubert and many of Kubert's former students, including Stephen R. Bissette, Amanda Conner, Rick Veitch, Eric Shanower, Steve Lieber, and Scott Kolins. Kubert's other granddaughter, Katie Kubert, became an editor for both DC and Marvel Comics.

Kubert was inducted into the Harvey Awards' Jack Kirby Hall of Fame in 1997 and the Will Eisner Comic Book Hall of Fame in 1998.
