Theta Tau

Theta Tau is the nation's foremost Fraternity for Engineers! 

Welcome to the official website of Theta Tau Professional Engineering Fraternity and the Theta Tau Educational Foundation!

From its start by four mining engineering students 112 years ago, Theta Tau has become the oldest and largest Fraternity for Engineers, with chapters across the country, and members around the world. Our mission is to develop ENGINEERING LEADERS for Service, Profession, and Brotherhood.

The fellowship, academic support and personal growth our Brothers find in Theta Tau make all the difference in their personal and professional success. In 2015, even more young leaders benefited from the undisputed value of the Theta Tau experience.  The Fraternity has more chapters & colonies, more student members, more alumni, doing more things, in more areas and interests, than ever before.  We call it The Theta Tau Difference.

Whether you are a visitor, parent, student, or alumnus, we hope you will take time to explore our website. Please contact us if we can be of assistance to you.

Educational Foundation


The Theta Tau Educational Foundation appreciates the generous support of our alumni and friends in furthering the development of our members, developing their leadership skills, and advancing their professional careers.  At this time of year, we give thanks for many things and many people -- and hope you can join others in making a contribution to support this mission.

2017 Membership Directory

Please visit the alumni page for more information.

Due to popular demand, Theta Tau is launching another Membership Directory project this summer. The published directory will be completed in mid-2017. 

We will be using Publishing Concepts, Inc. (PCI) once again for this project. They will reach out to members via phone, email, and mail to verify and update your information. Theta Tau and PCI respect your security and privacy concerns. 

Having partnered with them for what will be 5 directories over 25+ years, we have every confidence in their ability in this regard.
