A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure comprised of stars. Bars are found in approximately half of all spiral galaxies. Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well.Edwin Hubble classified these types of spiral galaxies as "SB" ("Spiral", "Barred") in his Hubble sequence, and arranged them into three sub-categories based on how open the arms of the spiral are. SBa types feature tightly bound arms, while SBc types are at the other extreme and have loosely bound arms. SBb type galaxies lie in between. A fourth type, SBm, was subsequently created to describe somewhat irregular barred spirals, such as the Magellanic Cloud galaxies, which were once classified as irregular galaxies, but have since been found to contain barred spiral structures.

Une galaxie spirale barrée, est une galaxie spirale dont les bras n'émergent pas du centre de la galaxie, mais d'une bande d'étoiles traversant ce centre. Les bras spiraux semblent émerger des bouts de la barre de ces galaxies, vu qu'elles paraissent émerger directement du noyau d'une galaxie spirale ordinaire.

Galaktyka spiralna z poprzeczką jest galaktyką spiralną z pasem jasnych gwiazd wychodzących z centrum i przebiegających przez środek galaktyki. Ramiona spiralne tych galaktyk wydają się wychodzić z końców "poprzeczki", podczas gdy w zwykłych galaktykach spiralnych wydają się wychodzić bezpośrednio z jądra.
