Hector Garrido (1928 – April 19, 2020) was an Argentine-born American book cover illustrator. He illustrated numerous science fiction, horror and adventure book covers, including all the covers for the Baroness series of pulp novels, and covers for the Destroyer series. He also illustrated romance and gothic novels, and Nancy Drew and Hardy Boys novels. He also did the painted artwork on G.I.Joe toy packaging of the 1980s. Some of his work is considered good girl art.

Garrido was born in Argentina and studied art in Buenos Aires. He emigrated to the United States, and began professional work there in the 1950s. After the 1990s he painted "devotional subjects".

Libraries appear to report that Garrido provided interior as well as cover illustrations for some of the "Susan Sand" mystery stories by Marilyn Ezzell.

Wikipedia book articles usually display front cover image of the first editions. Garrido may have provided cover art for a later edition.
