Multijet Final States in e+e- Annihilation

We review the current status of analyses of multijet final states in e+e- annihilation. Results for jet observables from LEP 1, LEP 2 and from the reanalysis of the PETRA experiment JADE will be presented. A determination of the b-quark mass using jet observables will be discussed and tests of power correction models will be shown. Finally determinations of the QCD colour factors from an analysis of event shape distributions at several energy points using power corrections will be discussed.
