Swedish organ builder born 6 June 1736 in Svärta parish, Södermanland, died 23 February 1815 in Linköping, Östergötland.

He came from Nyköping to Linköping in 1747 and in 1753 became an apprentice to organ builder Jonas Wistenius. As a first journeyman, Schiörlin later received independent assignments and in 1769 became Wistenius' partner. After the master's death in 1777, Pehr Schiörlin took over the workshop and was privileged in 1778. The organ building was located at Nygatan 17–19, where the buildings remained until the late 1960s, when they were demolished to make way for the current Gyllenhuset and Lilla torget. He lived in 1777 at Sankt Lars kvarter 46 in Linköping and from 1783 at Tannefors kvarter 42 in the same city.

He built around 60 organs, most of them in Östergötland and Småland. Many had more than 20 stops divided between two manuals and pedal. He built the first known work together with Jonas Wistenius in 1777 in Lindome Church in Halland. Schiörlin developed his own type of organ, characterized by an intense plenum sound with mixtures containing thirds, richness of color in the flute parts and reed parts of the highest quality, as well as separate principal parts in the treble position one octave below the foundation principal of the work.

Schiörlin died in 1815 in Linköping, whereupon the company was taken over by his son Jonas Fredric Schiörlin.
