A beach is a geological landform along the shoreline of a body of water, such as a lake, or the shore of an ocean or sea. It usually consists of loose particles which are often composed of rock, such as sand, gravel, shingle, pebbles, or cobblestones. The particles of which the beach is composed can sometimes instead have biological origins, such as shell fragments or coralline algae fragments.

Wild beaches are beaches which do not have lifeguards or trappings of modernity nearby, such as resorts and hotels. They are sometimes called undeclared, undeveloped, undefined, or undiscovered beaches. Wild beaches can be valued for their untouched beauty and preserved nature. They are found in less developed areas such as Puerto Rico, Thailand or Indonesia.

Beaches often occur along coastal areas where wave or current action deposits and reworks sediments.
