Warm inflation seems to be the most befitting single-field slow-roll inflation scenario in the context of the recently proposed swampland criteria. We investigate the constraints these swampland criteria impose on warm inflation parameters and show that warm inflation is in accordance with both the current cosmological observations and the proposed swampland criteria in both weak and strong dissipative regimes depending on the value of the parameter $c$, which limits the slope of the inflaton potential according to the criteria.
