"The Galactus Trilogy" is a 1966 three-issue comic book story arc that appeared in Fantastic Four #48–50. Written, co-plotted and drawn by Jack Kirby with editor Stan Lee for Marvel Comics, it introduced the characters Galactus and the Silver Surfer. In 2018, The Atlantic called it "the indisputable pinnacle of the so-called Silver Age of comic books".

Jack Kirby was an American comic book artist, widely regarded as one of the medium's major innovators and one of its most prolific and influential creators. He grew up in New York City and learned to draw cartoon figures by tracing characters from comic strips and editorial cartoons. He entered the nascent comics industry in the 1930s, drawing various comics features under different pen names, including Jack Curtiss, before settling on Jack Kirby. In 1940, he and writer-editor Joe Simon created the highly successful superhero character Captain America for Timely Comics, predecessor of Marvel Comics. During the 1940s, Kirby regularly teamed with Simon, creating numerous characters for that company and for National Comics Publications, later to become DC Comics.
