QCD results from LEP-1 and LEP-2

Recent results from QCD analyses at LEP1 and LEP2 are presented. High statistics LEP1 analyses make use of the very large data samples recorded at square root s approximately=M/sub Z/0 and provide detailed tests of perturbative QCD, QCD based Monte Carlo models and also of the differences between quark and gluon jets. The LEP2 analyses are based on very small data sets at high energy and provide general tests of QCD. Combined data on measurements of the strong coupling alpha /sub s/ from LEP1 and LEP2 give good evidence that in QCD a running coupling is preferred over a constant coupling. (57 refs).
