Delta Gamma was founded in 1873 in Oxford, Mississippi, at the Lewis School for Girls near the University of Mississippi. In 1891, Delta Gamma was one of the seven charter members of the National Panhellenic Conference when the first inter-sorority was held in Boston.

Delta Gamma is among the oldest of Women’s fraternities. More than 150,000 members have been initiated at the rate of 5,000 each year. Delta Gamma is established on nearly 140 college campuses across the United States and Canada.

Incorporated in 1951, the Delta Gamma Foundation includes such areas as Service for Sight; Scholarships, Fellowships, and Loans; Programming and Public Relations; and sponsorship of Art of the Eye. The Foundation is funded entirely by contributions from Delta Gamma collegiate chapters, alumnae groups, and individuals.

The Delta Lambda chapter of Delta Gamma was established on Mississippi State University's campus in 1969. Our chapter house, one of the largest in the Southeastern Conference, was built in 1988. It houses fifty ladies as well as our house director, Virginia Miller. The Delta Lambda chapter was awarded "Most Outstanding Chapter" for division one at the Delta Gamma Convention in June 2004
