The Chicago High School for Agricultural Sciences (CHSAS) is a public four-year magnet high school located in the Mount Greenwood neighborhood on the far south side of Chicago, Illinois, United States.

The students benefit from hands-on experience and summer internships, and many do go on to attend universities and major in agricultural disciplines.

CHSAS competes in the Chicago Public League and is a member of the Illinois High School Association (IHSA).

In 2012, CHSAS began a partnership with The Nature Conservancy's Leaders in Environmental Action for the Future (LEAF) program.

This program offers paid internships to a select number of students from CHSAS and helps staff develop resources.
