Pieter Rijsbraeck was a Flemish landscape painter, draughtsman and printmaker. He had an international career which brought him to England and Paris. His sons Pieter Andreas Rysbrack and John Michael Rysbrack were respectively a successful painter and sculptor in England in the 18th century.

Pieter Rijsbraeck was born in Antwerp where he was baptized on 25 April 1655. He was the son of Andries Rijsbraeck en Adriana Likens. He studied painting under the landscape painter Philips Augustijn Immenraet and was registered as a pupil in the Antwerp Guild of Saint Luke in 1672–1673. Not long after he left for England where he was active from c. 1675 to 1678.

He returned to Antwerp where he became a master in the Guild of Saint Luke in 1677–78. Not long after he left Antwerp again, this time for Paris where he was active for about ten years. Here he married Genoveva Compagnon, the widow of the Antwerp sculptor Philippe de Buyster who had died in Paris in 1688. Two of his sons became renowned artists in England: Pieter Andreas Rysbrack was a successful landscape and still life painter while John Michael Rysbrack was the leading sculptor in England in the mid 18th century. Another son named Gerard also became a painter. It is possible that the painter Jacques or Jacob Cornill Rijsbrack (1685–1765) was his son. If so this must have been with another spouse since Jacob was born before Pieter Rijsbraeck married Genoveva Compagnon in Paris. The genre painter Ludovicus Rijsbrack active around 1716–1717 in Antwerp may also have been a son of Pieter.

Pieter Rijsbraeck returned to Antwerp in 1689 (or possibly 1692) and was registered again as a master in the local Guild. His wife died in 1719.

After many years of activity in Antwerp he moved to Brussels in 1720. He died in Brussels in 1729.

His pupils included his sons Gerard and Pieter Andreas, and Karel Breydel.
