We report the discovery and validation of TOI 122b and TOI 237b, two warmplanets transiting inactive M dwarfs observed by \textit{TESS}. Our analysisshows TOI 122b has a radius of 2.72$\pm$0.18 R$_\rm{e}$ and receives8.8$\pm$1.0$\times$ Earth's bolometric insolation, and TOI 237b has a radius of1.44$\pm$0.12 R$_\rm{e}$ and receives 3.7$\pm$0.5$\times$ Earth insolation,straddling the 6.7$\times$ Earth insolation that Mercury receives from the sun.This makes these two of the cooler planets yet discovered by \textit{TESS},even on their 5.08-day and 5.43-day orbits. Together, they span thesmall-planet radius valley, providing useful laboratories for exploringvolatile evolution around M dwarfs. Their relatively nearby distances(62.23$\pm$0.21 pc and 38.11$\pm$0.23 pc, respectively) make them potentiallyfeasible targets for future radial velocity follow-up and atmosphericcharacterization, although such observations may require substantialinvestments of time on large telescopes.
