Pieter Andreas Rijsbrack (sometimes Anglicized as Peter Rysbrack) was a Flemish painter of still lifes and landscapes who was active in England in the first half of the 18th century. He is particularly known for launching the vogue of topographical views of English country houses and gardens. He was the older brother of the sculptor John Michael Rysbrack.

Pieter Andreas Rijsbrack was born in Paris as the son of the Antwerp landscape painter Pieter Rijsbraeck and his wife Genoveva Compagnon. His father had been working in Paris since c. 1678. Pieter Andreas moved with his parents to Antwerp around 1692. He learned to paint with his father and became a member of the Guild of St. Luke in Antwerp in 1711. He married the same year in Antwerp to Maria Anna van de Wee, the widow of the printmaker Cornelis Vermeulen. His wife died in 1718.

Pieter Andreas moved with his younger brother, the sculptor John Michael Rysbrack, to London around 1720. Pieter Andreas had more brothers who also became painters. One of these, the still life painter Gerard, joined him and John Michael in England.

John Michael Rysbrack became one of the leading sculptors in England and was particularly known for his portraits. As a sculptor to the elite, he was able to build a network of relationships with influential people in England. This served his brothers well as they were able to use these connections to gain commissions from prominent patrons.

One of Pieter Andreas most important commissions was the one he received from Lord Burlington to paint a series of country house portraits of Chiswick House. Rijsbrack thus took his place in a long tradition of Flemish painters who made topographical paintings of the estates of the British nobility which includes artists such as Jan Siberechts, Peter Tillemans and Hendrik Frans de Cort.

Pieter Andreas Rijsbrack died in London in October 1748, possibly of consumption.
