前桅横帆双桅船（brigantine）是一种两根桅杆的帆船，其前桅横帆，主桅纵帆。

前桅横帆双桅船有两根桅杆，前桅挂横帆，主桅挂纵帆。

与之相比，双桅横帆船两根桅杆上均为横帆；双桅纵帆船则两根桅杆上均为纵帆（schooner也泛指多桅纵帆船）。同为前桅横帆，主桅纵帆，若还有后桅甚至第四第五桅均挂纵帆则称为前桅横帆三桅船。

The brigantine was a two-masted sailing vessel with a fully square rigged foremast and at least two sails on the main mast: a square topsail and a gaff sail mainsail (behind the mast). The main mast is the second and taller of the two masts.

Modern American definitions include vessels without the square sails on the main mast.
