Alma Naturista is a Portuguese naturist association founded in 2017 to make naturism more accessible, responsible, and visible across Portugal. It promotes an approach grounded in respect for the body, other people, nature, and individual freedom, welcoming people to take part at their own pace. The association provides information for those curious about naturism, including beginner guidance, practical advice, legal context, and a map and directory of official and traditional naturist beaches, as well as other naturist places and accommodation.

Its programme brings the community together through year-round activities and regional groups. These include outdoor naturist yoga, nudist runs and walks, beach clean-ups, environmental volunteering, and photography projects. Alma Naturista also shares articles, community stories, event listings, and discussion through its blog, forum, and communication channels. Membership supports its information, activities, community projects, and public advocacy; the minimum annual fee is €3. The association offers a newsletter and a free introductory guide, and works with partners connected to naturist holidays, rural camping, wellbeing, and the promotion of naturism in Portugal.
