We present a measurement of the electric charge of top quarks usingevents produced incollisions at the Tevatron. The analysis is based on fully reconstructedpairs infinal states. Using data corresponding toof integrated luminosity, we exclude the hypothesis that the top quark has a charge ofat a significance greater than 5 standard deviations. We also place an upper limit of 0.46 on the fraction of such quarks that can be present in an admixture with the standard model top quarks () at a 95% confidence level.
