Abstract: It has been speculated that Lorentzian wormholes of the Morris-Thorne type might be allowed by the laws of physics at submicroscopic, e.g., Planck, scales and that a sufficiently advanced civilization might be able to enlarge them to classical size. The purpose of this paper is to explore the possibility that inflation might provide a natural mechanism for the enlargement of such wormholes to macroscopic size. A new classical metric is presented for a Lorentzian wormhole which is embedded in a flat de Sitter space. It is shown that the throat and the proper length of the wormhole inflate. The resulting properties and stress-energy tensor associated with this metric are discussed.
