The Optical Gravitational Lensing Experiment during its third stage (OGLE‐III) has collected a massive photometric database of hundreds of millions of stars, mainly in the Magellanic Clouds and the bulge of the Milky Way. This huge dataset is the base of a new catalog of variable stars—the largest such catalog in the history of astronomy. This paper describes the catalog of over 100 000 pulsating variables in the Large Magellanic Cloud: classical, type II and anomalous Cepheids, RR Lyrae stars, high amplitude δ Scuti stars and long period variables. We present some statistical features of these samples of pulsating stars and show particularly interesting individual objects.
