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 4 May 2005 from observations taken between 12 December 2004 and 9 March 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.
