Most students live on campus, in residence halls, apartments, or fraternity houses .
The residence halls often serve as centers of lively debate, peer counseling, and social life, and are an important part of the Gettysburg College experience. Gettysburg offers a variety of residential options. Students choose from 18 residence halls, including special interest houses that focus on specific topics like cultural diversity or fine arts, and theme halls dedicated to the sciences or substance-free housing. Several residence halls are reserved for first-year or upperclass students from varying class years and academic concentrations. First-year students live with members of their seminar section in the Residential College.
