'''Neko''' is a high-level [[Dynamic_programming|dynamically typed]] programming language developed by Nicolas Cannasse at [ Motion-Twin] as part of a R&D effort for better languages.

'''Neko''' is also the name used for a Virtual Machine bytecode interpreter. The VM can be embedded in applications via a C language API.

The '''nekoc''' command compiles Neko source code into NekoVM bytecode. The '''neko''' command runs NekoVM bytecode.

Another language, '''NekoML''', also compiles to NekoVM bytecode. '''nekoml''' is a higher level functional programming language, inspired by OCaml.

Other tools that ship with Neko, include a '''nekotools boot''' wrapper to create native executables that encapsulate NekoVM bytecode, and a small web server engine with embedded Neko. The '''nekotools server''' engine emulates the API provided by the Apache webserver plugin modules ''mod_neko'' and ''mod_tora''.

'''Neko''' is a core part of the [[Haxe]] programming language/toolkit; one of the output targets. Neko is used for system level access, command line applications, and takes a supporting role in some of the tools that make up the Haxe programming environment.

'''Neko''', introduced in 2005, may be superseded by a new virtual machine engine for Haxe development, [[HashLink]]. '''HashLink''' was introduced in 2016, designed as a successor to '''Neko'''. Haxe 4 (in preview in late 2018), still supports compilation to Neko bytecode and the '''Haxe 4''' environment still uses Neko library functions.
