The present invention relates to immunodominant epitope peptides of fibroblast activating proteins (FAPs), and uses thereof. The peptides of the present invention have excellent immunodominance and exhibit a strong effect of inducing CD8+ T cells specific for FAPs and FAP-expressing fibroblasts (FAP+ CAFs). The peptides of the present invention can exhibit excellent prevention and treatment effects on FAP-associated diseases such as cancer, fibrosis and NASH through immunity induction on FAPs, and has remarkably lower toxicity than other FAP-expressing CAF-targeted vaccines. Particularly, with respect to cancer, the peptides exhibit excellent anti-tumor effects such as depletion of FAP-expressing CAFs, decreased production of ECM in the TME, and suppressed cancer metastasis. If the peptides of the present invention are administered in combination with other anti-cancer agents, accumulation of the anti-cancer agent in tumor cells is increased and a remarkable improvement in anti-tumor effects is exhibited, and thus the peptides can be effectively used in pan-tumor vaccines.
