MACS0647\(-\)JD is a triply-lensed \(z\sim11\) galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647\(-\)JD as having two components that are either merging galaxies or stellar complexes within a single galaxy. Both are very small, with stellar masses \(\sim10^8\,M_\odot\) and radii \(r<100\,\rm pc\). The brighter larger component "A" is intrinsically very blue (\(\beta\sim-2.6\)), likely due to very recent star formation and no dust, and is spatially extended with an effective radius \(\sim70\,\rm pc\). The smaller component "B" appears redder (\(\beta\sim-2\)), likely because it is older (\(100-200\,\rm Myr\)) with mild dust extinction (\(A_V\sim0.1\,\rm mag\)), and a smaller radius \(\sim20\,\rm pc\). We identify galaxies with similar colors in a high-redshift simulation, finding their star formation histories to be out of phase. With an estimated stellar mass ratio of roughly 2:1 and physical projected separation \(\sim400\,\rm pc\), we may be witnessing a galaxy merger 400 million years after the Big Bang. We also identify a candidate companion galaxy C \(\sim3\,{\rm kpc}\) away, likely destined to merge with galaxies A and B. The combined light from galaxies A+B is magnified by factors of \(\sim\)8, 5, and 2 in three lensed images JD1, 2, and 3 with F356W fluxes \(\sim322\), \(203\), \(86\,\rm nJy\) (AB mag 25.1, 25.6, 26.6). MACS0647\(-\)JD is significantly brighter than other galaxies recently discovered at similar redshifts with JWST. Without magnification, it would have AB mag 27.3 (\(M_{UV}=-20.4\)). With a high confidence level, we obtain a photometric redshift of \(z=10.6\pm0.3\) based on photometry measured in 6 NIRCam filters spanning \(1-5\rm\mu m\), out to \(4300\,Å\) rest-frame. JWST NIRSpec observations planned for January 2023 will deliver a spectroscopic redshift and a more detailed study of the physical properties of MACS0647\(-\)JD.
