The invention relates to a process for preparing fluoroanilines of the formula (I) FnArNH2 (I) in which n is 1, 2, 3 or 4, Ar is phenyl, naphthyl or pyridyl, and the remaining substituents on the Ar radical are identical or different and are, independently of each other, hydrogen, halogen, (C1-C4)-alkyl, phenyl, NR2, OR, CN, CHO, or COR, where R is hydrogen or (C1-C6)-alkyl, wherein fluoronitrobenzenes of the formula (II) XmFnArNO2 (II) in which n, Ar and the remaining substituents on the Ar radical have the abovementioned meaning, X is chlorine or bromine and m is 1, 2, 3 or 4, are reacted with hydrogen in the presence of a palladium catalyst, of an amine which is not soluble in water and which also does not form watersoluble hydrohalides, and, where appropriate, of an inert solvent.
