LLVM er en compiler-infrastruktur skrevet i C++. LLVM var i starten en forkortelse af Low Level Virtual Machine, men dette ligger nu så langt fra den nuværende funktion, at LLVM officielt ikke længere er et akronym.[2]
LLVM er designet til compile-time-, link-time-, runtime- og "idle-time"-optimering af programmer skrevet i vilkårlige programmeringssprog. I starten blev kun C og C++ implementeret – i dag er der flere sprog, som også kan oversættes med LLVM: Objective-C, Fortran, Ada, Haskell, Java bytecode, Python, Ruby, ActionScript, GLSL og Rust.
LLVM-projektet startede i 2000 ved University of Illinois at Urbana–Champaign, under ledelse af Vikram Adve og Chris Lattner.
LLVM benytter Clang som C/C++-compiler-frontend.

'LLVM' is officially no longer an acronym. The acronym it once expanded too was confusing, and inappropriate almost from day 1. :) As LLVM has grown to encompass other subprojects, it became even less useful and meaningless.
