A pocket is a small bag, particularly a bag-like recepticle either fastened to or inserted in an article of clothing.

The word appears in Middle English as poket, and is taken from a Norman diminutive of O. Fr. poke, pouque, mod. poche, cf. pouch. The form poke is now only used dialectically, or in such proverbial sayings as "a pig in a poke," and possibly in the poke-bonnet , the coal-scuttle bonnet fashionable during the first part of the 19th century, and now worn by the female members of the Salvation Army; more probably the name of the bonnet is connected with poke, to thrust forward, dig. The origin of this is obscure. Dutch has poken, pook, a dagger; Swedish pk, a stick.

A fob pocket is a small pocket designed to hold an old style pocket watch in mens' trousers and vests.

Historically, the term pocket referred to:

• A pouch worn around the waist by women in the 17th to 19th centuries, mentioned in the rhyme Lucy Locket if interpreted literally. [1]
• A sack in which hops were stored, generally with a capacity of 168 to 224 lb (76 to 102 kg).

The term pocket park has come into use to describe a small area accessible to the general public that is often of primarily environmental, rather than recreational, importance.

A pocket can also refer to the anal cavity or orifice such as in the phrase: Carlee would like to put Spencer in her pocket.
