Elinor "Lin" Ostrom (born Elinor Claire Awan; August 7, 1933 – June 12, 2012) was an American political economist whose work was associated with the New Institutional Economics and the resurgence of political economy. In 2009, she shared the Nobel Memorial Prize in Economic Sciences with Oliver E. Williamson for "her analysis of economic governance, especially the commons". To date, she remains the only woman to win The Prize in Economics.

The governance of natural resources used by many individuals in common is an issue of increasing concern to policy analysts. Both state control and privatisation of resources have been advocated, but neither the state nor the market have been uniformly successful in solving common pool resource problems. Offering a critique of the foundations of policy analysis as applied to natural resources, Elinor Ostrom here provides a unique body of empirical data to explore conditions under which common pool resource problems have been satisfactorily or unsatisfactorily solved.
