<P>ABSTRACT</P><P>We present a mosaic image of the 1.4-GHz radio continuum emission from the Large Magellanic Cloud (LMC) observed with the Australia Telescope Compact Array (ATCA) and the Parkes Telescope. The mosaic covers <IMG SRC='http://onlinelibrary.wiley.com/store/10.1111/j.1365-2966.2007.12466.x/asset/equation/MNR_12466_mu1.gif?v=1&s=3c55d39c3da8b7009e1ce58371b88f172bd55796'/> with an angular resolution of 40 arcsec, corresponding to a spatial scale of ∼10 pc in the LMC. The final image is suitable for studying emission on all scales between 40 arcsec and the surveyed area. In this paper, we discuss (i) the characteristics of the LMC's diffuse and compact radio continuum emission, (ii) the fraction of the emission produced by thermal processes and the implied star formation rate in the LMC and (iii) variations in the radio spectral index across the LMC. Two non-standard reduction techniques that we used to process the ATCA visibility data may be of interest for future wide-field radio continuum surveys. The data are open to the astronomical community and should be a rich resource for studies of individual objects such as supernova remnants, H <SMALL>II</SMALL> regions and planetary nebulae as well as extended features such as the diffuse emission from synchrotron radiation.</P>
