Bebhionn (/bɛˈvn/ be-VEEN) or Saturn XXXVII (37) (provisional designation S/2004 S 11) is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on May 4, 2005, from observations taken between December 12, 2004, and March 9, 2005.

Bebhionn is about 6 kilometres in diameter and orbits Saturn at an average distance of 16,898 Mm in 820.130 days at an inclination of 41° to the ecliptic (18° to Saturn's equator) and with an eccentricity of 0.333. The rotation period was measured by the ISS camera of the Cassini spacecraft to ~16 hours.[1]

It was named in April 2007 after Bébinn, an early Irish mythology goddess of birth, who was renowned for her beauty.
