Artus Quellinus II or Artus Quellinus the Younger (alternative first name: Arnold; variation on family name: Quellijn, Quellyn, Quellien, Quellin, Quellinius) (between 10 and 20 November 1625 – 22 November 1700) was a Flemish sculptor who played an important role in the evolution of Northern-European sculpture from High Baroque to Late Baroque.

Artus Quellinus II received many commissions from patrons in the Southern Netherlands as well as from other cultural centres of Europe, such as Copenhagen.

Artus the Younger's emphasis on emotion reveals a link with the work of Bernini and Lucas Faydherbe (1617–1697), the leading sculptor from Mechelen who had trained with Peter Paul Rubens.

This is reflected in his preference for graceful bodies, flowing draperies, hair that is tussled by the wind and fine facial expressions with little sense of realism.

The statue of St. Rosa of Lima in St. Paul's Church in Antwerp is an example of his more contemplative style and is regarded as one of the most beautiful sculptures from the Baroque in the Southern Netherlands.
