Pasco High School is a 9–12 public high school in Pasco, Washington. It was the only high school in Pasco until 2009, when Chiawana High School was opened.

In 2006, Pasco voters approved a $90 million+ bond to construct a new high school on Argent and Road 84 to ease the overcrowding of Pasco High. The new Chiawana High School opened in fall of 2009 along Argent Road. During the time of construction, Pasco High turned Captain Gray STEM Elementary School into an annex, where a majority of freshman classes were held. Once Chiawana High opened, the building once again became Captain Gray Elementary. Additionally, the school makes use of over 50 portable classrooms.
