We present the first measurement of the production cross section of a W boson with a single charm quark (c) in pp collisions at {radical}(s)=1.96 TeV, using soft muon tagging of c jets. In a data sample of {approx}1.8 fb{sup -1}, recorded with the Collider Detector at Fermilab II detector at the Fermilab Tevatron, we select events with W+1 or 2 jets. We use the charge correlation between the W and the muon from the semileptonic decay of a charm hadron to extract the Wc signal. We measure {sigma}{sub Wc}(p{sub Tc}>20 GeV/c,|{eta}{sub c}|<1.5)xBR(W{yields}l{nu})=9.8{+-}3.2 pb, in agreement with theoretical expectations.
