Saturn LXVII, provisionally designated S/2004 S 7, 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 8 March 2005.
Saturn LXVII is about 6 kilometres in diameter, and orbits Saturn at an average distance of 21,559,000 kilometres in about 1,182 days, at an inclination of 165.0° to the ecliptic, in a retrograde direction and with an eccentricity of 0.574.[3][5] Denk et al. (2018) tentatively assigned this moon to the Mundilfari dynamical family, but it may instead be more closely related to Thrymr.[6]
This moon was considered lost[7] until its recovery was announced on 12 October 2022.[3] On 14 April 2026, the Minor Planet Center gave the moon its Roman numeral designation Saturn LXVII (Saturn 67).[8]
