Paul-Louis Huvelin (1873–1924), generally known as Paul Huvelin, was a French legal historian.

He was a specialist in the study of the earliest forms of Roman law.

Huvelin spent almost all his career teaching in the law faculty of the University of Lyon which he joined in 1899. That year he made contact with the anthropologist Marcel Mauss and, as a result, gradually became involved with the group of pioneer French sociologists organised by Mauss' uncle Emile Durkheim. Huvelin, as a respected jurist, was welcomed into the Durkheim group and contributed regularly to Durkheim's famous L'Année Sociologique yearbook, from its sixth volume, published in 1906, until the series was suspended on the outbreak of the First World War. Huvelin made important contributions to the sociological study of the earliest forms of Western law. His imaginative if sometimes speculative scholarship explored links between magic and the emergence of ideas of private rights. He also tried to reformulate Durkheim's own ideas of law to make them more compatible with the instrumental legal outlook of jurists.

Towards the end of his life he became involved with efforts to shore up waning French influence in the Middle East. As an offshoot of the Lyon law faculty's involvement with legal education in territories associated with France, he was instrumental in the founding of the law school of the Université Saint-Joseph in Beirut in 1913. In 1919 he led a mission to Syria to assess the growing threats to French interests in the region. He died after a short illness in 1924.

A street in Beirut, is named after him, the Rue Huvelin.
