During the debates over the design and ratification of the United States Constitution, in 1787 and 1788, a large number of writers in the popular press used pseudonyms. This list shows some of the more important commentaries and the (known or presumed) authors responsible for them. Note: the identity of the person behind several of these pseudonyms is not known for certain.
|Agrippa||James Winthrop||Eighteen essays appeared under this name in the Massachusetts Gazette between November 23, 1787 and February 5, 1788.|
|Americanus||John Stevens, Jr.|
|Aristedes||Alexander Contee Hanson||Federalist.|

|Brutus||Robert Yates, Melancton Smith||Anti-Federalist. After Marcus Junius Brutus, a Roman republican involved in the assassination of Caesar. Published sixteen essays in the New York Journal between October 1787 and April 1788.|
|Centinel||Samuel Bryan||Alternately, the author possibly was George Bryan.|
|Cincinnatus||Arthur Lee||After Lucius Quinctius Cincinnatus. Six essays addressed to James Wilson appeared under this name in the New York Journal beginning November 1, 1787.|
