This site is a dynamic, issue-by-issue, appearance-by-appearance, chronology of the DC Comics character, Supergirl. It lists every comic in which Supergirl featured in a story, including single-panel cameos. For convenience, the chronology is broken up into three eras: Classic Kara Zor-El, Matrix/Cir-El, and (as yet unavailable) Modern Kara Zor-El. For more details, consult the FAQ.

The Classic Kara Zor-El era was initially created to aid the writing of "Supergirl: the Life and Times of Kara Zor-El". It has been hosted free to all Supergirl fans thanks to SuperWomenMania.com.

The author would like to acknowledge the Supergirl Maid of Might fan web site and the Grand Comics Database, both of which proved very useful in compiling the Matrix era timeline. SWM forum user, and fellow Supergirl enthusiast, TwiceOnThursdays suggested a handful of missing cameos and corrected odd mistakes. The DC Comics Wikia was also helpful in double checking certain credits and dates.
