We present a search for ZZ and ZW vector boson pair production in pp collisions at {radical}(s)=1.96 TeV using the leptonic decay channels ZZ{yields}ll{nu}{nu}, ZZ{yields}lll{sup '}l{sup '}, and ZW{yields}lll{sup '}{nu}. In a data sample corresponding to an integrated luminosity of 194 pb{sup -1} collected with the Collider Detector at Fermilab, 3 candidate events are found with an expected background of 1.0{+-}0.2 events. We set a 95% confidence level upper limit of 15.2 pb on the cross section for ZZ plus ZW production, compared to the standard model prediction of 5.0{+-}0.4 pb.
