Matthias Dropa (born between 1646[1] and 1665[2] – 25 September 1732) was a German organ builder.
A pupil of Arp Schnitger, he built organs in Northern Germany, including St. Michaelis, Lüneburg.
He moved to Lüneburg in 1705, where he built a new organ at St. Michaelis, together with his assistant Gerhard von Holy [de].
From 1712 to 1715, he expanded the organ of St. Johannis, supervised by Georg Böhm by a pedal.
[1] The organ builder Johann Matthias Hagelstein [de] married his daughter Catharina Margaretha on 22 June 1734.
