Jacob Cornelisz Schout (c.1600 - after 1627), was a Dutch Golden Age member of the Haarlem schutterij.
He was born in Haarlem as the son of the judge Cornelis Jacobsz Schout, and was a flag bearer of the white brigade (and therefore bachelor) of the St. George militia in Haarlem from 1612 to 1627. He was portrayed three times in schutterstukken: by Frans Hals in The Banquet of the Officers of the St George Militia Company in 1616, by Pieter de Grebber in 1619, and again by Hals in The Banquet of the Officers of the St George Militia Company in 1627. He was succeeded as a flag bearer by Pieter Schout.
He died in Haarlem.
