A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall, consisting of an orange shield bearing a gold sword with blade up, the blade surmounted by a gold open book, with edges of the pages black, on the page to the viewer's left an orange heart below three orange peaks; on the page to the viewer's right the orange head of a beaver. Attached below the shield a segmented black scroll inscribed "OREGON STATE" on the viewer's left and "UNIVERSITY" on the viewer's right in gold letters.
Orange and black are the colors of the University. The sword alludes to leadership and to military science. The open book represents knowledge. The beaver, known for its ingenuity and abilities, is indicative of the nickname of the University's athletic teams. The heart below the peaks refers to "CORVALLIS" (from the Latin word meaning heart of the valley). The peaks are symbolic of Mary's Peak, the highest peak in the coast range. Together the two refer to the location of the University.
The shoulder loop insignia was authorized 5 February 1981.
