# List of Phi Delta Theta chapters

Phi Delta Theta is an international college fraternity founded in 1848. Chapter designation is determined by the order in which each chapter was awarded its charter in the state or province in which it is located (i.e., the first chapter established in a state/province is designated "Alpha", the second is "Beta", the third "Gamma", and so on). Exceptions to this rule have occurred when two universities, each with their own chapter, merge, causing the chapters to merge. This results in the hyphenated name of the two chapters that make up the new one (see Illinois Delta-Zeta).

## Provinces

Phi Delta Theta groups chapters together in a province to assist with the administration of its many chapters. Each province has a Greek letter as its name.
