Pascack Hills High School (PHHS) is a four-year comprehensive public high school, one of two secondary schools serving students in ninth through twelfth grade as part of the Pascack Valley Regional High School District in Bergen County, in the U.S. state of New Jersey. PHHS serves the residents of both Montvale, where the campus is located, and the neighboring community of Woodcliff Lake. The other high school in the district is Pascack Valley High School, which serves the communities of Hillsdale and River Vale.
 As of the 2021–22 school year, the school had an enrollment of 827 students and 71.6 classroom teachers (on an FTE basis), for a student–teacher ratio of 11.6:1. There were 3 students (0.4% of enrollment) eligible for free lunch and 3 (0.4% of students) eligible for reduced-cost lunch.
 The school opened in September 1964, having been built to alleviate crowding at the district's original facility, Pascack Valley High School, which had been opened in 1955. Constructed at a cost of $2.9 million (equivalent to $27.4 million in 2022), the facility was designed with a system of folding walls that could be adjusted to handle student groups of varying sizes. The district received a $12,000 grant from a unit of the Ford Foundation that would allow the school to use IT&T computer systems run by a senior program analyst from that firm that would allow students to select classes on their own. The school spent its first five decades relatively unchanged in terms of architecture. In 2006, an extra gym was added. Most recently, the new science wing was opened as well as a new entrance building. This school is one of the first locally to provide every student with a laptop, which can be taken home, and be used in school every day. Every classroom is fitted with a wireless access point (IEEE 802.11 a/g/n), which provides the students with internet. For the 2007–08 school year, the school upgraded all of its laptop computers to Apple MacBooks.
 Pascack Hills High School was the 7th-ranked public high school in New Jersey out of 339 schools statewide in New Jersey Monthly magazine's September 2014 cover story on the state's "Top Public High Schools", using a new ranking methodology.

The magazine ranked the school 12th in 2008 and was ranked 8th in the magazine's September 2006 issue, which included 316 schools across the state. The school's peak rating by New Jersey Monthly was in 2001 at 2nd. Schooldigger.com ranked the school 46th out of 381 public high schools statewide in its 2011 rankings (a decrease of 29 positions from the 2010 ranking) which were based on the combined percentage of students classified as proficient or above proficient on the mathematics (93.0%) and language arts literacy (97.0%) components of the High School Proficiency Assessment (HSPA).
 In its 2013 report on  "America's Best High Schools", The Daily Beast ranked the school 345th in the nation among participating public high schools and 27th among schools in New Jersey.
 In the 2011 "Ranking America's High Schools" issue by The Washington Post, the school was ranked 62nd in New Jersey and 1,782nd nationwide. In Newsweek's May 22, 2007 issue, ranking the country's top high schools, Pascack Hills High School was listed in 1194th place, the 40th-highest ranked school in New Jersey.
 Pascack Hills High School's athletic facilities include a regulation size track, a turf football field named for long-time principal Bart DiPaola, four tennis courts, a combination softball and baseball field that can be utilized for soccer, and two gymnasiums, which house basketball and volleyball.

 The Pascack Hills Broncos compete in Colonial Division A of the North Jersey Interscholastic Conference (NJIC), which is comprised of public and private high schools located in Bergen, Hudson and Passaic counties, and was established following a reorganization of sports leagues in Northern New Jersey by the New Jersey State Interscholastic Athletic Association (NJSIAA). Before the 2010 realignment, the school was one of the 12 high schools participating in the North Bergen Interscholastic Athletic League (NBIL/NBIAL). With 607 students in grades 10–12, the school was classified by the NJSIAA for the 2019–20 school year as Group II for most athletic competition purposes, which included schools with an enrollment of 486 to 758 students in that grade range. The football team competes in the American Red division of the North Jersey Super Football Conference, which includes 112 schools competing in 20 divisions, making it the nation's biggest football-only high school sports league. The school was classified by the NJSIAA as Group II North for football for 2022–2024, which included schools with 478 to 672 students.
 Formerly known as the "Cowboys", while Pascack Valley was the "Indians", the old team names were eliminated by the district at a July 2020 board meeting. In March 2021, the Board of Education ratified new team names that had been selected by a vote of students and staff at each school, with Pascack Hills being renamed the Broncos and Pascack Valley adopting the Panthers as its new team name.
 In 2004, the football team joined the Bergen-Passaic Scholastic League (BPSL), to play against other schools of similar enrollment size. Citing lower enrollment, and the loss of Hillsdale and portions of River Vale to Pascack Valley as a result of redistricting, Pascack Hills left the North Bergen Interscholastic Athletic League (NBIAL) for football only and played an independent schedule for two seasons, as PHHS was classified by the NJSIAA as a Group I school (the smallest of the four classifications) and all of the other schools in the league were Group II or Group III schools. Prior to the NJSIAA's realignment that took effect in the fall of 2010, Pascack Hills was a member of the NBIAL for most sports. Pascack Hills is the only former NBIAL school in the NJIC, joining Queen of Peace High School and Rutherford High School as the only two schools moved to the NJIC that had not come directly from the Bergen County Scholastic League National / Olympic divisions or from the BPSL.
 School colors are brown and white with orange. Sports offered include cheerleading, dance, cross-country, football, boys' and girls' soccer, tennis, volleyball, gymnastics, basketball, bowling, ice hockey, swimming, wrestling, Winter Track, baseball, softball, and lacrosse.
 The school participates as the host school / lead agency in a joint cooperative gymnastics team with Pascack Valley High School, while Pascack Valley is the host school for ice hockey and boys / girls swimming teams. These co-op programs operate under agreements scheduled to expire at the end of the 2023–24 school year.
