Apollinaris Patera is the former name of Apollinaris Mons, a shield volcano on Mars's surface. It is situated near the equator in the south hemisphere, southeast of the shield volcano Elysium Mons on the Elysium Planitia, and north of Gusev crater.

Apollinaris Mons is about 5 kilometres high with a base about 296 kilometres in diameter. [ [http://www.google.com/mars/#lat=-9.058702&lon=177.121582&zoom=6&q=Apollinaris%20Patera Google Mars ] ] On the top of this volcano is a small crater with an irregular border (the "patera"), which was probably made by an explosive, or pyroclastic, eruption. The volcano is approximately 3 billion years old [ [http://apod.nasa.gov/apod/ap990513.html APOD: May 13, 1999 - Mars Volcano Apollinaris Patera ] ] or possibly 3.5 bilion years old.

It was named in 1973 after a mountain spring near Rome in Italy.
