The Quarterly Journal of Economics is a peer-reviewed academic journal published by the Oxford University Press for the Harvard University Department of Economics.

Its current editors-in-chief are Robert J. Barro, Lawrence F. Katz, Nathan Nunn, Andrei Shleifer, and Stefanie Stantcheva.

It is the oldest professional journal of economics in the English language,[1] and second-oldest in any language after the Zeitschrift für die gesamte Staatswissenschaft [de].

It covers all aspects of the field—from the journal's traditional emphasis on micro-theory to both empirical and theoretical macroeconomics.

[2] It is generally regarded as one of the top 5 journals in economics, together with the American Economic Review, Econometrica, the Journal of Political Economy, and The Review of Economic Studies.
