Theta Tau - The Nation's Foremost Fraternity for Engineers!

Welcome to the official website of Theta Tau Professional Engineering Fraternity and the Theta Tau Educational Foundation! Theta Tau is the nation's oldest and largest Fraternity for Engineers. Our mission is to develop Engineering Leaders for Service, Profession, and Brotherhood.

The Theta Tau Difference

The fellowship, academic support and personal growth our Brothers find in Theta Tau make all the difference in their personal and professional success.   In 2011, even more young leaders benefited from the undisputed value of the Theta Tau experience. We call it The Theta Tau Difference.

We need your help to continue moving forward. Every gift to the Theta Tau Foundation not only supports the brotherhood that you remember, it also helps ensure that The Theta Tau Difference lives on for future generations. Donate now 

From its start by four mining engineering students over 106 years ago, Theta Tau has become the oldest and largest professional engineering fraternity with chapters across the country and members around the world.
