H2BSP is the node builder and map compiler originally used by Raven Software for Hexen. Like DoomEd and HereticEd, it is a NeXTSTEP application written in Objective-C, complicating the creation of cross-platform ports. It is a derivative of DoomBSP, enhancing support for Hexen's maps, and was created by John Romero.

Since it was designed to compile maps created by HereticEd into their binary form, it does not read map lumps such as THINGS, VERTEXES or LINEDEFS. Instead, it parses a text file in DWD format which contains the map information and creates said lumps from it.

Unlike DoomBSP, its source code was not released, however the basis for H2BSP is rooted in the original DoomBSP source code.
