Jan Collaert II or Hans Collaert II was a Flemish engraver and printmaker working in Antwerp around the turn of the 17th century. Collaert also published under the name Jan Baptist Collaert.

Jan Collaert was the son of Anna van der Heijde and Jan Collart I and the brother of Adriaen Collaert. He trained under his brother Adriaen as well as with leading Antwerp engravers Philip Galle and Gerard de Jode. He became member of the Antwerp Guild of Saint Luke in 1585 and was the Guild's dean in 1612.

From 1580 through his death c. 1620, Collaert and his brother were both employed by Philip Galle, one of the most prolific print publishers in Europe during the late sixteenth century. The brothers both married a daughter of Galle. Jan married in the late 1590s with Elisabeth Galle, after he became a widower of Elisabeth Firens, whom he had married in 1595. The last entry on Jan Collaert II in the Guild's records dates from the yearbook 1620/21.

His pupils included Barbara van den Broeck and Antony van der Does.
