SNNS (Stuttgart Neural Network Simulator) is a neural network simulator originally developed at the University of Stuttgart. While it was originally built for X11 under Unix, there are Windows ports^{[ citation needed]}. Its successor JavaNNS never reached the same popularity.

SNNS is written around a simulation kernel to which user written activation functions, learning procedures and output functions can be added. It has support for arbitrary network topologies and the standard release contains support for a number of standard neural network architectures and training algorithms.

There is currently no ongoing active development of SNNS. In July 2008 the license was changed to the GNU LGPL.
