A sorority is a social club for women at a college or university, usually combining residential facilities with shared dining and recreation areas. Like fraternities, sororities are customarily identified by Greek letters, and admit members on the basis of mutual compatibility.

The organization is a women's social club associated with a college or university. Its residential arrangements commonly include shared dining and recreation spaces.

General student housing assigned without sorority membership has a different arrangement. A fraternity is the corresponding men's social-club form.
