"In The Garden Of Iden" (1997) is the debut novel of science fiction author Kage Baker. It is also the first novel in the "Company" series.

The novel introduces Mendoza, an operative of "Dr. Zeus Incorporated", or more commonly: the Company. The Company is an immensely powerful corporation in the 24th century, which preserves works of art and extinct forms of life by recruiting orphans from the past, making them as good as immortal and sending them into the past on specific missions. Mendoza is rescued from the Spanish Inquisition and sent to Elizabethan England to collect botanical samples from the garden of Sir Walter Iden.

"In The Garden Of Iden" combines some of Kage Baker's strongest passions: she is an authority on Tudor-era England, has a strong interest in botany, and a preoccupation with conspiracy theories. The author (on her personal website) mentions that many of the characters in the novel were inspired by the eccentric scholars and street actors she worked with during her career in theater.
