PBS News Hour, previously stylized as PBS NewsHour, is an American evening television news program broadcast on over 350 PBS member stations since October 20, 1975. It airs seven nights a week, and is known for its in-depth coverage of issues and current events. Since January 2, 2023, the one-hour weekday editions have been anchored by Amna Nawaz and Geoff Bennett. The 30-minute weekend editions that premiered on September 7, 2013, branded as PBS News Weekend, have been anchored by John Yang since December 31, 2022.

The broadcasts are produced by PBS member station WETA-TV in Washington, D.C., and originates from its studio facilities in Arlington County, Virginia. Since 2019, news updates inserted into the weekday broadcasts targeted for viewers in the Western United States, online, and late at night have been anchored by Stephanie Sy, originating from the Walter Cronkite School of Journalism and Mass Communication at Arizona State University. Additional production facilities for the program are based in San Francisco and Denver. The program is a collaboration between WETA-TV and PBS member station WNET in New York City, along with KQED in San Francisco, KETC in St. Louis, and WTTW in Chicago.

The program debuted in 1975 as The Robert MacNeil Report before being renamed The MacNeil/Lehrer Report one year later. It was anchored by Robert MacNeil from WNET's studios and Jim Lehrer from WETA's studios. In 1983, the show was rebranded as The MacNeil/Lehrer NewsHour, and then The NewsHour with Jim Lehrer following MacNeil's departure in 1995. It was then renamed to its current PBS NewsHour title in 2009, two years before Lehrer left in 2011. Originally, the program only aired on weekdays before weekend editions began in 2013. Production of the weekend broadcasts were solely produced by WNET, before the New York City station transferred all of its PBS NewsHour involvement to WETA in April 2022.
