Siuslaw High School is a public high school in the northwest United States, located in Florence, Oregon.^[1] It is named after the local Siuslaw River, and the current principal is Michael Harklerode.^[1][4]

Siuslaw High School was originally located on Quince Street in Florence. The athletic field consisted of a cinder track with a dirt infield, behind the junior high school, which both the junior and senior high schools utilized. The "Hans Peterson Memorial Field" was located southwest of both schools, on 2nd street. The former high school building has been demolished and, as of 2021, the lot is vacant.

The current school was first occupied in September 1970, with the class of 1971 being its first graduating class. In 1970, the location of the school was considered outside city limits, and students who lived in town had to be bussed to the school or, as many did, walked, drove or found other means of transport. The area's student population comes from a larger general region, with individuals coming from the north at Sea Lion Caves, east to Tiernan, up the North Fork of the Siuslaw, south to the county line and all points east of Woahink and Siltcoos lakes (Canary). Both the middle and high schools still share the track and football field, now located at the middle school. In the summer of 2019, the track was resurfaced.
