We study if eternal inflation is realized while satisfying the recently proposed string swampland criteria concerning the range of scalar field excursion, |Δφ|<D·MP, and the potential gradient, |V|>c·V/MP, where D and c are constants of order unity and MP is the reduced Planck mass. We find that only the eternal inflation of chaotic type is possible for c∼O(0.01) and 1/D∼O(0.01) and that the Hubble parameter during the eternal inflation is parametrically close to the Planck scale and is in the range of 2πcHinf/MP<1/3.
