DuVal High School (DHS) is a comprehensive science and technology public magnet high school in the Seabrook census-designated place in unincorporated Prince George's County, Maryland, United States, with a Lanham postal address.

[1][2] Prior to 2010 the U.S. Census Bureau defined the area containing DuVal High as being within the Goddard CDP.

The original building was a one-story, 38-classroom school situated in the formerly small village of Good Luck, Maryland.

DuVal held a number of public offices, including serving as the U.S. representative from Maryland's second district from November 11, 1794, to March 28, 1796, Chief Justice of Maryland's General Court from 1796 to 1802, and U.S. Comptroller of the Treasury from 1802 through 1811.

Duvall also served on the United States Supreme Court, as associate justice (replacing fellow Marylander Samuel Chase) from 1811 until 1835, when he resigned due to old age.
