In punctuation, the full stop (Commonwealth English) or period (American English) is a punctuation mark placed at the end of a sentence. The full stop glyph is sometimes called a baseline dot because, typographically, it is a on the baseline. This term distinguishes the baseline dot from the interpunct (a raised dot).

• "Full Stop", a song by Frank Klepacki
• A campaign by the National Society for the Prevention of Cruelty to Children, intended to prevent child abuse.
• The Full Stop Law (Ley de Punto Final), the 1986 bill signed by Argentine President Raúl Alfonsín limiting civil trials against those implicated in the Dirty War to those indicted within 60 days of the law's passage.
