This article is about a molecular dynamics application and force field. For more meanings of the word Amber, see Amber (disambiguation). AMBER (an acronym for Assisted Model Building and Energy Refinement) is a family of force fields for molecular dynamics of biomolecules originally developed by the late Peter Kollman's group at the University of California, San Francisco. AMBER is also the name for the molecular dynamics simulation package that implements these force fields. It is maintained by an active collboration between David Case at The Scripps Research Institute, Tom Cheatham at the University of Utah, Tom Darden at NIEHS, Ken Merz at Florida, Carlos Simmerling at Stony Brook University, Ray Luo at UC Irvine, and Junmei Wang at Encysive Pharmaceuticals.

Amber is the common name for fossil resin or tree sap that is appreciated for its inherent and interesting mixture of colours and it is widely used for the manufacture of ornamental objects. Although not mineralized, it is sometimes considered and used as a gemstone. Most of the world's amber is in the range of 30–90 million years old. Semi-fossilized resin or sub-fossil amber is called copal.
