'''Saturn LX''', provisionally known as '''S/2004 S 29''', is a natural satellite of Saturn and a member of the Gallic group. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, and Jan Kleyna on October 7, 2019 from observations taken between December 12, 2004 and January 17, 2007.<ref name="announcement">{{cite web |title=MPEC 2019-T136 : S/2004 S 29 |url=https://minorplanetcenter.net/mpec/K19/K19TD6.html |website=minorplanetcenter.net |accessdate=7 October 2019}}</ref> It was given its permanent designation in August 2021.<ref name="MPC133821">{{cite web|title=M.P.C. 133821|url=https://www.minorplanetcenter.net/iau/ECS/MPCArchive/2021/MPC_20210810.pdf|website=Minor Planet Center|publisher=International Astronomical Union|date=10 August 2021|access-date=21 August 2021}}</ref>
Saturn LX is about 4 kilometres in diameter, and orbits Saturn at an average distance of {{convert|17|e6km|e6mi|abbr=unit}} in {{cvt|837.78|d|yr}}, at an average inclination of 38.6° to the ecliptic, with an eccentricity of 0.485.<ref name="jplsats-elem"/>
Saturn LX was initially thought to be part of the Inuit group before it was recategorized to the Gallic group in 2022.<ref name="Jacobson2022"/>{{rp|page=7}}
