An up‐to‐date global compilation of crustal thickness and Pn velocity values from published seismic refraction and surface wave data has been created. From 297 referenced sources, a total of 2508 crustal thickness and 1806 Pn velocity values have been selected. This represents a significant expansion of previous compilations. The inclusion of surface wave data results in a more uniform coverage of the earth's surface than is possible by using only published refraction data. The crustal thickness data are contoured on a global Van der Grinten projection. This compilation currently resides in a computer data base and is available on computer compatible tape. Recommendations for improvement in form and content will be welcomed, as periodic updates are anticipated.
