An organizer is someone who arranges things, brings people together, or plans events to make them run smoothly. A community organizer might gather neighbors to clean up a local park or start a book club. A labor organizer helps workers form unions so they can negotiate better wages and working conditions. When Martin Luther King Jr. and Rosa Parks fought for civil rights, they worked as organizers, bringing people together to stand up for justice through peaceful protests and meetings.

The word also refers to objects that help keep things tidy and findable. A desk organizer holds pens, paper clips, and sticky notes in separate compartments. A closet organizer creates spaces for shoes, shirts, and other clothes. Some people use digital organizers or phone apps to track appointments and homework assignments.

What makes someone a good organizer? They think ahead, notice what needs doing, and figure out how to coordinate different people or things. The class representative who organizes a field trip needs to arrange transportation, collect permission slips, and make sure everyone knows the schedule. An organizer sees the whole picture and helps all the pieces come together, whether that means planning a surprise party, supporting a protest movement, or simply keeping a backpack from turning into a crumpled mess of papers.
