Johann Georg Fischer (21 January 1673 – 26 April 1747) was a stonemason and builder.

He stood for a long time in the shadow of his famous uncle, Johann Jakob Herkomer (1652–1717).

[1] Fischer's son Franz Karl later stepped into his father's professional footsteps.

His works include the Parish church of St. Gallus and Ulrich in Kißlegg, where there is also a road named after him.
