A short overview of the current state of Chiral Perturbation Theory is given. This includes a description of the basic assumptions, the usefulness of the external field method is emphasized using a simple lowest order example. Then at next-to-leading order the determination of the parameters is discussed. We also present the status of calculations at \cal O(p6). Finally I present the extension into 3 directions: estimates of the free parameters, inclusion of nonleptonic weak and electromagnetic interactions, and inclusion of non-Goldstone fields in the chiral Lagrangian. Invited Talk at the International Workshop on Nuclear & Particle Physics ``Chiral Dynamics in Hadrons & Nuclei,'' Feb 6 ∼ Feb 10, 1995, Seoul, Korea.
