Johann Balthasar Lauterbach (20 May 1663, Ulm - 20 April 1694, Wolfenbüttel) was a German mathematician, architect and master builder at the Court in Braunschweig, from 1688 until his death.
In 1687, Anthony Ulrich, Duke of Brunswick-Wolfenbüttel, assigned him to the Rudolph-Antoniana, a Ritterakademie in Wolfenbüttel, where he taught mathematics and architecture. Two years later, he was appointed Master Builder, in charge of a new princely Building Authority, assisted by Hermann Korb. In 1692, he became the Fortress Engineer and proceeded to expand the city's fortifications.
He died in 1694, following a long illness, aged only thirty. Korb succeeded him as Master Builder and Leonhard Christoph Sturm [de] took his place at the Ritterakademie.
His treatise, Compendium Architecturae Civilis Harmonicae Antiquae et Novae, was published posthumously in Amsterdam in 1698.
