The section sign (Unicode U+00A7§SECTION SIGN, HTML §, TeX \S) is a typographical character used mainly to refer to a particular section of a document, such as a legal code. It is also called "double S" and "sectional symbol".

The likely origin of the section sign is the digraph formed by the combination of two S glyphs (from the Latin signum sectiōnis). When duplicated, as §§, it is read as the plural "sections" (e.g. "§§ 13–21"), much as "pp." (pages) is the plural of "p."
