Philippe Frémeaux (1 October 1949 – 3 August 2020) was a French economic journalist with the magazine Alternatives économiques.

As a consultant, Frémeaux worked for Le BIPE from 1983 to 1999, where he led numerous advisory missions for the French Ministry of Industry and the European Commission.

He then joined the writing staff of Alternatives économiques, a monthly magazine with which he voluntarily contributed.

In 1988, he became editor-in-chief, and then succeeded Denis Clerc as head of the company which oversees the magazine from 1999 to 2012.

In addition to Le Monde and Alternatives économiques, Frémeaux has also contributed to France Info and France Culture, notably on the program C dans l'air.
