In 1582, Gentili published De Juris Interpretibus Dialogi Sex.
This book shows Gentili as a staunch supporter of the bartolist method and an opponent of the French humanist jurists like Jacques Cujas, who applied philological methods to the sources of Roman law.

Gentili's first book on issues of international law was De Legationibus Libri Tres, published in 1585.

Between 1588 and 1589 Gentili published three booklets collected as De Jure Belli Commentationes Tres.
An enhanced edition appeared under the title De Jure Belli Libri Tres in 1598.
It is considered his main work and a classic of public international law.
The book is praised for its modernity and its skillful use of civil law concepts but also for its closeness to the actual practice of international law.

Gentili published De armis Romanis in two parts in 1590 and 1599.
While less studied than his earlier works, De armis Romanis has been the focus of recent scholarly attention by Christopher N. Warren, Diego Panizza and others.

After his death, Alberico Gentili's brother Scipione, who had become a professor of law at Altdorf, published a collection of notes on cases Alberico had worked on as an advocate for the Spanish embassy.
The book bears the title Hispanicae Advocationis Libri Duo and appeared in 1613.
