Chiawana High School

Chiawana High School is a four-year public high school in Pasco, Washington, United States, the second traditional high school of Pasco School District #1. Opened in 2009 with 1600 students in grades 9, 10, and 11, CHS graduated its first senior class in 2011. The school colors are blue and silver and the mascot is a riverhawk.

Chiawana's campus features its own athletic facilities, which include a lighted football/soccer field surfaced with FieldTurf, negating the need to use Edgar Brown Memorial Stadium on the other end of town. The school's gymnasium was used by both Chiawana and Pasco High School for the 2009–2010 school year, as the main gymnasium at Pasco High had an unanticipated roof replacement.

The school's principal is Jaime Morales.
