Lady Penelope was a British weekly comic book magazine for girls which ran from 1966 to 1969.

[2] The title character was based on Lady Penelope Creighton-Ward, the secret agent seen in the Gerry & Sylvia Anderson/AP Films television series Thunderbirds.

City Magazines began publishing Lady Penelope annuals in 1967, continuing for six editions until 1972.

This merger appears to have been arranged hastily and would have left some of the weekly comic strip serials unfinished, so the endings of these were included in the form of text stories in issue #204.

Despite the combined title, only one comic serial from Penelope survived the merge, albeit with the format and main character's name altered.
