Jonas Ekengren (1736–1793) was a Swedish craftsman known for his work as both a chair maker and an organ builder. Born in Stora Mellösa, Örebro County, he was the son of soldier Eric Ekengren and Annicka Andersdotter. Initially working as a mason in Stockholm, Ekengren later became a professional chair builder. In 1760, he received a privilege from the Board of Trade as a chair maker and became a member of the guild. By 1766, he had transitioned to organ building, constructing numerous organs, primarily for the Uppsala Diocese. Despite being self-taught and lacking formal qualifications, Ekengren became a significant figure in the Swedish organ-building scene of the 18th century.

Ekengren married four times and had several children. His first marriage was to Maria Elisabeth Norberg in 1756, with whom he had five children. After her death, he married Antonetta Ulrica Lindberg in 1768, and they had three children. His third marriage was to Margareta Catharina Kihlberg, and his fourth to Anna Magdalena Sparrman, with whom he had one daughter. Ekengren's notable contributions to organ building include working with the organ builder Mattias Swahlberg the Younger and constructing organs for various churches in Sweden. He passed away in Stockholm in 1793 and was buried in the Maria Magdalena parish.
