We present results from a search for solar axions with the COSINE-100 experiment. We find no evidence of solar axion events from a data-set of 6,303.9 kg$cdot$days exposure and set a 90,% confidence level upper limit on the axion-electron coupling, $g_{ae}$, at 1.70~$times$~$10^{-11}$ for an axion mass less than 1,keV/c$^2$. This limit excludes QCD axions heavier than 0.59,eV/c$^2$ in the DFSZ model and 168.1,eV/c$^2$ in the KSVZ model.
