Fast Green FCF, also called Food green 3, FD&C Green No. 3, Green 1724, Solid Green FCF, and C.I. 42053, is a turquoise triarylmethane food dye. Its E number is E143.

Fast Green FCF is recommended as a replacement of Light Green SF yellowish in Masson's trichrome, as its color is more brilliant and less likely to fade. It is used as a quantitative stain for histones at alkaline pH after acid extraction of DNA. It is also used as a protein stain in electrophoresis. Its absorption maximum is at 625 nm.

Fast Green FCF is poorly absorbed by the intestines.^[2] Its use as a food dye is prohibited in the European Union and some other countries. In the United States, Fast Green FCF is the least used of the seven main FDA approved dyes.
