Delta Gamma (ΔΓ), commonly known as DG, is a sorority in the United States and Canada with over 250,000 initiated members.
It has 151 collegiate chapters in the United States and Canada and more than 200 alumnae groups. The organization's executive office is in Columbus, Ohio. The Delta Gamma Foundation gives more than 150,000 volunteer service hours and raises hundreds of thousands of dollars annually for scholarships and grants for its members, schools and assistance for the visually impaired, and support for U.S. veterans. In 2013, Delta Gamma founded the #IAmASororityWoman campaign. This movement calls on members of any sorority to spark meaningful conversations about what sorority women truly value, in an effort to combat common stereotypes.
Delta Gamma is one of 26 national sororities which are members under the umbrella organization of the National Panhellenic Conference.
