The Center for Research in Security Prices, often known by its acronym CRSP, is a research centre at the Booth School of Business of the University of Chicago.

It maintains the most comprehensive collection of security price, return, and volume data for the NYSE, AMEX and NASDAQ stock markets. Additional CRSP files provide stock indices, beta- and cap-based portfolios, treasury bond and risk-free rates, and mutual fund databases. 

It also provides CRSP/Compustat Merged Database, a database that simplifies matching COMPUSTAT financial data to the CRSP security price data.
