NeoPlanet was a Trident-shell graphical web browser initially released in 1997 by New York based Bigfoot International, Inc. and later maintained and developed by its subsidiary NeoPlanet, Inc. It was one of the first browsers to be fully skinnable.

The Neoplanet program was originally created by James Friskel. Neoplanet Inc. was a subsidiary of Bigfoot International, Inc. Both companies were founded by Lenny Barshack and James Hoffman.

A beta version of a trident shell NeoPlanet was released in October 1997, one month after Internet Explorer 4.0 release. It featured a built-in directory of channels further divided into categories and was for use with Windows 95 and NT. In the fall of 1998 Bigfoot released the NeoPlanet 2.0 version with a new feature of customizable interface. It was positioned as an alternative to Netscape, Microsoft's and AOL offerings. The new version also featured Snap (a joint-venture between CNET and NBC) and Alexa services incorporated into the browser.. The free 1.9MB download was a significant interface upgrade with four skins included and 16 more available on the newly launched NeoPlanet site, while the Microsoft Internet Explorer`s underlying features remained unchanged.
