Single-issue interest groups are advocacy groups comprised of members who are passionate about one particular issue. Oftentimes, these groups come together to lobby against specific government legislation, and they work together in an effort to get others to support their cause.

Single-interest groups sometimes represent specific people, causes or organizations with common concerns and interests. There are thousands of single-interest groups in the United States, and these groups focus on a wide array of issues, such as animal rights, abortion, foreign policy, police brutality, gay rights and gun control. One of the most popular and influential single-issue groups in the United States is the National Rifle Association, which is an organization that supports and promotes the legal use of guns and defends each U.S. citizen's constitutional right to bear arms.

Other popular single-interest groups include the National Abortion Rights Action League, Mothers Against Drunk Driving, the National Association for the Advancement of Colored People, Gay and Lesbian Advocates and Defenders and the National Coalition Against Domestic Violence. Many single-interest groups are also not-for-profit organizations that operate out of small offices within specific communities, and those who lead these groups keep members abreast of any new legislation while also providing information and support to members of the community.
