Sigma Phi Delta () is an international professional-social fraternity of engineers. As "The Premier International Fraternity of Engineers", the organization is the only fraternity of its kind that draws its membership exclusively from male engineering students at ABET-accredited colleges and universities, as other similar organizations are co-ed or admit students not strictly in traditional engineering programs (such as architecture or technical sciences).
Sigma Phi Delta was founded at University of Southern California on April 11, 1924 and currently has 25 active chapters.
The Alpha chapter of Sigma Phi Delta was founded on April 11, 1924 in the third attempt to establish an engineering fraternity at the University, the other two having been terminated into general fraternities. Unlike many fraternities at USC, the Alpha chapter owns its historic house. The chapter house originally served as a foreign government consulate.
The Delta chapter of Sigma Phi Delta was founded on January 25, 1928 by a group of students that included a brother of an Alpha chapter Founder and an Alpha chapter Alumnus in graduate school. Delta chapter has produced 5 Grand Presidents who have guided the fraternity 46 of its 80+ years of existence. The only two members who have been named Grand Old Men of Sigma Phi Delta Fraternity were Delta Alumni.
The Epsilon chapter of Sigma Phi Delta was founded on May 21, 1928. They have the annual Peddle-for-Pets Philanthropy in the fall semester. They are also involved in a local initiative called "Tech Boyz" that hosts weekly Engineering related information based session for different age groups, depending on grade.
The Eta chapter of Sigma Phi Delta was founded on May 23, 1931 when a local Marquette Engineering Fraternity, Omega Sigma Phi, merged with the National Fraternity. Eta chapter has the largest number of registered alumni in the entire Sigma Phi Delta Organization, with over 900 living alumni worldwide, and is Marquette University's oldest active fraternity.
The Theta chapter of Sigma Phi Delta was founded on April 24, 1932. Once under the IFC, it is now under the EUS of UBC's Engineering Department.
The Kappa chapter of Sigma Phi Delta was founded on May 25, 1947. The Kappa chapter is located at Trine University located in Angola, Indiana. This chapter was established during an engineering undergraduate boom at Tri-State College (former name) following WWII and the G.I. Bill.
The Rho chapter of Sigma Phi Delta was founded on Dec 18, 1965. After deactivating, the Rho chapter was rechartered on April 18, 2015.

Its Country Committee, the first of any fraternity nationwide, was founded on May 2, 2018 on US Route 158, slightly South of the Virginia-North Carolina border by brothers Anthony Mahshigian and Thomas Casey. After Casey's graduation in 2020, he self-appointed Jim Townsend to assume his seat as country co-chair. This established a precedent for the transfer of power to future country committee leaders, and cemented the Country Committee's everlasting legacy.
The Beta-Kappa chapter of Sigma Phi Delta was founded on March 23, 2013. Based in Bethlehem, Pennsylvania, in the P.C. Rossin College of Engineering and Applied Sciences.

Motto: Sigma Phi Delta, in upper and lower case Greek letters
The Name of the Fraternity is represented by the capital form of the Greek letters Sigma (?), Phi (?), Delta (?) which stand for Science, Friendship and Duty.
The Pledge Pin is described as: "A red triangular background on which is a black Castle, the whole bordered in gold".
The Membership Badge is described as: "A triangle having concave corners on which are superimposed three smaller triangles having concave sides and having their vertices at the center of the badge on which is placed a ruby. The smaller triangles, which contain the letters Sigma, Phi and Delta, are black, the background between them being white. A gold star is located near each of the vertices of the large triangle. The border may be engraved gold or may be jeweled. The crown pearl badge has four pearls on each side of the badge. The ruby point badge has two rubies and two pearls on each side, the pearls being in the middle and the rubies at the outside".
The fraternity flag is 4' × 6' cotton bunting or nylon. The design is black letters, bordered with white and a gold Castle on a red field. This is a standard flag, that is, read correctly from left to right on one side and in reverse on the other.
In 2015, Sigma Phi Delta and Alpha Omega Epsilon joined together to form a strategic partnership with the FIRST Robotics Competition in order to fulfill their respective mission to further Engineering Education. Together, they plan to advocate and promote career opportunities in STEM, within grades K-12 as well as higher education, build on existing STEM related programs, and seek ways to engage their memberships in FIRST Mentor/Coach opportunities as a means of workforce development, increased community involvement and/or encourage employees to give back to the communities where they live/work. Most Sigma Phi Delta chapters were already involved with their respective communities FIRST teams, but this further cements Sigma Phi Delta's object of further Engineering as a whole.
