Gridgen is a commercial mesh generator developed, distributed, and supported by Pointwise, Inc. in Fort Worth, Texas, USA. Development of Gridgen began in 1984 and commercialization began in 1994.

The last production release of Gridgen was Version 15.18, released in August 2012.

Gridgen's end-of-life went into effect in September 2016.
