Oecotraustes is an extinct cephalopod genus included in the ammonid family Oppeliidae and named by Wilhelm Waagen in 1869.

Species in the genus lived during the Middle Jurassic.

[1] The shell of Oecotraustes is evolute, the outer whorl only moderately embracing the inner whorls, laterally compressed whorl height greater than width.

[citation needed] Fossils of Oecotraustes species have been found in Jurassic sediments of Germany, India, Madagascar, Spain, and the United States.
