George Pérez (June 9, 1954 – May 6, 2022) was an American comic book artist and writer, who worked primarily as a penciller. He came to prominence in the 1970s penciling The Avengers for Marvel Comics, and returned to the franchise in the 1990s. In the 1980s he penciled The New Teen Titans, which became one of DC Comics' top-selling series. He penciled DC's landmark limited series Crisis on Infinite Earths, followed by relaunching Wonder Woman as both writer and penciller for the rebooted series. In the meantime, he worked on other comics published by Marvel, DC, and other companies into the 2010s. He was known for his detailed and realistic rendering, and his facility with complex crowd scenes.

In October 2013, Pérez revealed that he would soon undergo laser and injection surgeries to address hemorrhaging in his left eye that had effectively made him blind in that eye. By the following June, the procedures were not yet completed, but his condition had improved to the point that he was able to resume his work. In May 2017, he was admitted to a hospital with chest pains due to a heart attack while traveling to a convention, and had a coronary stent fitted. By January 2019, Perez was dealing with multiple health issues, including diabetes and problems with his vision and his heart.

In December 2021, he revealed that after undergoing surgery for a blockage in his liver, he had been diagnosed with inoperable pancreatic cancer. Given a prognosis of 6 to 12 months, he chose not to pursue treatment. In early 2022, both DC and Marvel included tributes to him and his work in their comics, and jointly approved a limited-run reprint of the 2003 JLA/Avengers story he illustrated (long tied up by disagreements between the rival publishers), as a benefit for The Hero Initiative.
