The Sociedade Portuguesa de Física (SPF), or Portuguese Physical Society, is a professional and scholarly association dedicated to physics in Portugal. It brings together members through subject-focused divisions covering areas such as astronomy and astrophysics, atomic and molecular physics, condensed matter, nuclear and particle physics, medical physics, optics and lasers, geophysics, and the history and education of physics. The society supports communication and knowledge-sharing through its Gazeta de Física, which publishes articles and offers subscriptions, author submissions, and advertising opportunities.

SPF also organizes meetings, conferences, training activities, and other events, and provides information about its regional delegations, membership, and newsletters. Its website highlights initiatives in science education, including the MEDEA project, physics competitions and Olympiads, and recognition of achievement in teaching and research. SPF also shares news from the European Physical Society and other scientific organizations, helping connect Portugal’s physics community with wider developments.

Through these publications, events, educational programs, and specialist networks, the society serves students, educators, researchers, and others interested in physics
