Jerôme Duquesnoy (II) or Hieronymus Duquesnoy (II) or the Younger (baptized 8 May 1602 – 28 September 1654) was a Flemish architect and sculptor who was particularly accomplished in portraits. He played an important role in the introduction of the Baroque style in Northern European sculpture.

Manneken Pis is a landmark 55.5 cm (21.9 in) bronze fountain sculpture in central Brussels, Belgium, depicting a puer mingens; a naked little boy urinating into the fountain's basin. Though its existence is attested as early as the mid-15th century, Manneken Pis was redesigned by the Brabantine sculptor Jérôme Duquesnoy the Elder and put in place in 1619. Its stone niche in rocaille style dates from 1770. The statue has been repeatedly stolen or damaged throughout its history. Since 1965, a replica has been displayed, with the original stored in the Brussels City Museum.
