This page contains philatelic information on the Mars Odyssey satellite. Catalog numbers, years of issue, and notes on the satellites featured are given when available. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page.

The use of the MO acronym/initialism is not recommended, to avoid confusing Mar Odyssey with Mars Observer.

The Mars Surveyor 2001 Orbiter mission after being canceled was later renamed Mars Odyssey.
