We present the first Doppler image of the rapidly-rotating K0III star of the single-lined RS CVn binary UZ Librae. Our analysis incorporates line profile variations from three spectral regions (around CaI 6439A, FeI 6411A and FeI 6393A) and continuum variations from simultaneous VRI photometry. All images recover a polar feature consisting of mainly three "appendages" between latitudes of +60deg and +80deg. This polar feature is not like a polar cap as previously seen on other RS CVn stars but consists primarly of the three appendages. Up to six equatorial features were also detected and have temperature differences between 200 and 400K cooler than the photospheric temperature of 4800K. Images from individual spectral lines show an encouraging amount of consistent detail, especially for the location but also for the shape of certain features. The recovery of the temperature scale is on average also similar but can be somewhat different for particular surface features. This is most noticeable for the larger of the three polar appendages; we found it 30% cooler from the CaI line and the FeI 6411-A line than from the FeI 6393-A line. We suspect such differences are partially due to external errors of the line profile data and slightly inaccurate input physics. New photometry and radial velocity measurements are used to recompute the photometric period and the orbital elements of UZ Librae.
