Naturalistic pantheism or scientific pantheism is a naturalistic form of belief that encompasses feelings of reverence and belonging towards Nature and the wider Universe, concern for the rights of humans and all living beings, care for Nature, and celebration of life. It is realist and respects reason and the scientific method. It is based on philosophical naturalism and as such it is without belief in supernatural realms, afterlives, beings or forces.

The core of Naturalistic Pantheism is reverence for the real Universe, as progressively revealed by the scientific method and by our senses. Thus Naturalistic Pantheism does not believe in any creator deity distinct from nature, rather nature itself is the self-creating source of all being. Although Naturalistic Pantheism does not include belief in a personal afterlife, it does promote the idea of naturalistic afterlife in the form of genetic inheritance, persistence through memories as the result of actions in this life, and recycling of human physical elements in Nature to continue the cycle of life.
