The James Webb Space Telescope (JWST) will be able to probe the atmospheresand surface properties of hot, terrestrial planets via emission spectroscopy.We identify 18 potentially terrestrial planet candidates detected by theTransiting Exoplanet Survey Satellite (TESS) that would make ideal targets forthese observations. These planet candidates cover a broad range of planet radii($R_{\rm p} \sim 0.6 - 2.0 R_\oplus$) and orbit stars of various magnitudes($K_s = 5.78 - 10.78$, $V = 8.4 - 15.69$) and effective temperatures ($T_{\rmeff }\sim 3000 - 6000$ K). We use ground-based observations collected throughthe TESS Follow-up Observing Program (TFOP) and two vetting tools -- DAVE andTRICERATOPS -- to assess the reliabilities of these candidates as planets. Wevalidate 13 planets: TOI-206 b, TOI-500 b, TOI-544 b, TOI-833 b, TOI-1075 b,TOI-1411 b, TOI-1442 b, TOI-1693 b, TOI-1860 b, TOI-2260 b, TOI-2411 b,TOI-2427 b, and TOI-2445 b. Seven of these planets (TOI-206 b, TOI-500 b,TOI-1075 b, TOI-1442 b, TOI-2260 b, TOI-2411 b, and TOI-2445 b) areultra-short-period planets. TOI-1860 is the youngest ($133 \pm 26$ Myr) solartwin with a known planet to date. TOI-2260 is a young ($321 \pm 96$ Myr) Gdwarf that is among the most metal-rich ([Fe/H] = $0.22 \pm 0.06$ dex) stars tohost an ultra-short-period planet. With an estimated equilibrium temperature of$\sim 2600$ K, TOI-2260 b is also the fourth hottest known planet with $R_{\rmp} < 2 \, R_\oplus$.
