Phycology (from Greek , phykos, "seaweed"; and , ) is the scientific study of algae. Also known as algology, phycology is a branch of life science and often is regarded as a subdiscipline of botany.

Algae are important as primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms that live in a wet environment. They are distinguished from the higher plants by a lack of true roots, stems or leaves. They do not flower. Many species are single-celled and microscopic (including phytoplankton and other microalgae); many others are multicellular to one degree or another, some of these growing to large size (for example, seaweeds such as kelp and Sargassum).

Phycology includes the study of prokaryotic forms known as blue-green algae or cyanobacteria. A number of microscopic algae also occur as symbionts in lichens.

While both the ancient Greeks and Romans knew of algae, and the ancient Chinese even cultivated certain varieties as food, the scientific study of algae began in the late 18th century with the description and naming of Fucus maximus (now Ecklonia maxima) in 1757 by Pehr Osbeck. This was followed by the descriptive work of scholars such as Dawson Turner and Carl Adolph Agardh, but it wasn't until later in the 19th century that efforts were made by J.V. Lamouroux and William Henry Harvey to create significant groupings within the algae. Harvey has been called "the father of modern phycology" in part for his division of the algae into four major divisions based upon their pigmentation.
