Martin Binder (born October 17, 1849, in Ilmmünster; died August 1, 1904, in Regensburg) was a German organ builder.

Martin Binder was born on October 17 in Ilmmünster. After leaving school around the age of 14, around the year 1862/63, he learned the trade of a carpenter. In 1865, he went on a journey to further his skills and during this time, he also learned the trade of organ building. The exact places where he worked are not recorded, but it is likely that he spent time with Max Maerz, as it was the only progressive company at that time already dealing with cone chests. In 1875, Binder founded an organ-building company in Pfaffenhofen an der Ilm, which he moved to Regensburg in 1890, along with his brother-in-law Willibald Siemann, to Villastraße 2, in the eastern expansion area of Regensburg. From this point, the company was known as "Binder & Siemann."

In 1900, the company split: the Munich branch operated under "Siemann & Co" while the original Regensburg workshop became "Martin Binder & Sohn," as Binder's son Eugen had joined the business in 1895. By the time of the founder's death in 1904, the company had built 140 organs, mostly with pneumatic cone chests. Eugen Binder, who died around 1957, took over the business until he emigrated to America in 1909. Thereafter, the Regensburg branch functioned only as a branch of "Willibald Siemann & Co."
