Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America).

It is maintained by the Missouri Botanical Garden and was established in 1982.

The database contains images and taxonomical and bibliographical data on more than 4.2 million herbarium specimens.

The database can be queried in English, French, and Spanish.

[1] Tropicos was developed by Garden botanist Dr. Robert Magill in the early 1980s, initially on a tiny Osborne 01 microcomputer.
