Logo & Seal

Caltech uses a multilevel system of visual symbols to consistently identify the Institute in all communication materials: the Caltech logo (the primary mark), and the Caltech seal (a formal, ceremonial mark).

On this page, you will find guidelines on how to appropriately use these marks, and how to pair them with your organization, department, or division name. A selection of spirit marks, reserved for use by athletics and recreation are also available; these marks do not represent Caltech as an institution.


"Caltech" is our preferred name and should be used in all references.

The official name, "California Institute of Technology" should be used only in legal documents and formal uses, such as diplomas.

Our logo reflects the Institute's stature and reputation by emphasizing the Caltech name. The logo should be used to represent Caltech in all communications except the most formal, for which the seal is reserved.
