Abstract. Frobenius groups arise naturally in various questions of group cohomology,
differential geometry, algebraic topology, etc. We will show that k(G) is retract
k-rational if G is a Frobenius group and k is an infinite field satisfying very mild
conditions. As an application, we will show that, if k is any algebraic number field,
G is a Frobenius group whose complement is isomorphic to
