Je passe en revue l’impact récent de l’astrométrie fournie par la mission spatiale Gaia dans le domaine des exoplanètes, tant en termes de caractérisation des orbites et des masses des systèmes planétaires que des propriétés de leurs étoiles hôtes. Je discute ensuite des résultats récemment publiés dans la troisième livraison majeure des données (DR3), qui commencent à aborder la science des exoplanètes sur la base des seules données de Gaia. Je conclus par un regard prospectif sur les contributions majeures à notre compréhension de la démographie des exoplanètes, attendues à partir des futures publications de données Gaia.

I review the recent impact of Gaia astrometry in the exoplanet field, both in terms of characterization of the orbits and masses of planetary systems and the properties of their host stars. I then discuss the newly published results in the third major data release (DR3), that begin to tackle exoplanetary science based on Gaia data alone. I conclude with a perspective look at the expectations for major contributions to our understanding of exoplanet demographics from future Gaia data releases.
