The Public Broadcasting Service (PBS) is an American public broadcaster and non-commercial, free-to-air television network based in Arlington, Virginia. PBS is a publicly funded nonprofit organization and the most prominent provider of educational programming to public television stations in the United States, distributing shows such as Frontline, Nova, PBS NewsHour, Arthur, Sesame Street, and This Old House.

PBS is funded by a combination of member station dues, the Corporation for Public Broadcasting, pledge drives, and donations from both private foundations and individual citizens. All proposed funding for programming is subject to a set of standards to ensure the program is free of influence from the funding source. PBS has over 350 member television stations, many owned by educational institutions, nonprofit groups both independent or affiliated with one particular local public school district or collegiate educational institution, or entities owned by or related to state government.

As of 2020, PBS has nearly 350 member stations around the United States.
