Richfield High School was a school formerly located in Waco, Texas. The school began construction in 1960 and opened in September 1961. It was situated on the site of a World War I army airfield, Rich Field.

In 1986, Richfield was consolidated with two other high schools in Waco ISD — Waco High School and Jefferson-Moore High School. This merged school, the current Waco High School, is housed in the former Richfield building on N. 42nd Street in Waco.

The Richfield school mascot was the Ram and school colors were scarlet (red) and gray.

The most celebrated athletic success at Richfield was back-to-back Texas state girls' basketball championships in 1984 and 1985. The Richfield Ramblers (changed from Rams) completed both seasons with undefeated records and had a combined record of 66–0, one of the greatest accomplishments in Texas high school basketball history.
