Alexander W. Dreyfoos School of the Arts (DSOA) is a public high school in West Palm Beach, Florida. Formerly named the Palm Beach County School of the Arts (also known as "School of the Arts" or "SOA"), the school was renamed in recognition of a 1997 donation of $1 million by Alexander W. Dreyfoos, Jr., a West Palm Beach philanthropist. It is regularly ranked as one of the top public arts and academics schools in the country.

DSOA is administrated by the School District of Palm Beach County, which also provides most of its funding. The school receives supplementary funds for its arts and academics from the School of the Arts Foundation, Inc., a 501(c)(3) non-profit organization.
