Nonsectarian institutions are secular institutions or other organizations not affiliated with or restricted to a particular religious group.

Pi Lambda Phi (ΠΛΦ or Pi Lam) is a college social fraternity founded by Frederick Manfred Werner, Louis Samter Levy, and Henry Mark Fisher at Yale University in 1895. It was founded as the first nonsectarian fraternity, "a fraternity in which all men were brothers, no matter what their religion; a fraternity in which ability, open-mindedness, farsightedness, and a progressive, forward-looking attitude would be recognized as the basic attributes." It currently boasts 35 chapters and four colonies in the United States and one chapter in Canada. The fraternity founded the Pi Lambda Phi Fraternity Educational Foundation

The first nonsectarian sorority was Phi Sigma Sigma. Phi Sigma Sigma (ΦΣΣ), colloquially known as "Phi Sig", was the first collegiate nonsectarian sorority to welcome women of all faiths and backgrounds. Founded by ten women on November 26, 1913, at Hunter College in New York, Phi Sigma Sigma is now an international sorority with 60,000 initiated members, 115 collegiate chapters, and more than 100 alumnae chapters, clubs, and associations across the United States and Canada.

Delta Phi Epsilon sorority, founded in 1917, was the first nonsectarian social sorority founded at a professional school.

Legal usage
A 1956 amendment to the constitution of the State of Virginia allowed for tuition grants to be paid by the state to nonsectarian private schools.

Blaine amendments to thirty-eight state constitutions forbid direct government aid to educational institutions with a religious affiliation. The typical wording, "religious sects or denominations," is most often used to challenge support to Catholic parochial schools (38% of private school attendance); Protestant schools with an undifferentiated "Christian" often get a pass. These schools often claim both "nonsectarian" and "Christian" in their promotional materials. The United States Department of Education differentiates Christian from Conservative Christian in its analyses.

Non-academic institutions
Organizations that are explicitly nonsectarian include the Apex Clubs of Australia, those participating in the Ethical Culture Movement, the National Jewish Medical and Research Center, and the Tibetan Buddhist Center of Philadelphia. In Northern Ireland, nonsectarian refers to groups identifying themselves as neither Republican or Unionist, such as the Alliance Party of Northern Ireland, Green Party Northern Ireland, People Before Profit or the Police Service of Northern Ireland.
