'''Lysithea''' ({{lang-el|Λυσιθέα}}) adalah [[satelit ireguler]] [[prograde]] [[Jupiter]]. Lysithea ditemukan oleh [[Seth Barnes Nicholson]] pada tahun 1938 di [[Observatorium Mount Wilson]]<ref name="Nicholson 1938"/> dan dinamai berdasarkan tokoh mitologis [[Lisitea]], putri dari [[Okeanos]] dan salah satu selir [[Zeus]].<ref name="IAUC 2846">{{cite web |last=Marsden |first=Brian G. |title=Satellites of Jupiter |publisher= [[International Astronomical Union]] |date=1975-10-07 |url=http://www.cbat.eps.harvard.edu/iauc/02800/02846.html}}</ref>
Lysithea tidak mendapat nama sekarang hingga tahun 1975. Sebelumnya, Lysethia dikenal sebagai '''{{nowrap|Jupiter X}}'''. Satelit ini kadang disebut pula sebagai "[[Demeter]]"<ref name="Gaposchkin">{{cite book| last=Payne-Gaposchkin|first=Cecilia|author2=Katherine Haramundanis |title=Introduction to Astronomy| url=https://archive.org/details/introductiontoas0000payn|date=1970|publisher=[[Prentice-Hall]]|location=Englewood Cliffs, N.J.|isbn=0-13-478107-4}}</ref> dari tahun 1955 hingga 1975.
Lysithea termasuk dalam [[kelompok Himalia]], kelompok satelit yang mengorbit Jupiter dengan jarak antara 11 dan 13 Gm dari Jupiter dengan inklinasi sekitar 28,3°.<ref name="Jacobson 2000"/> Elemen orbitnya berdasarkan data bulan Januari 2000. Mereka secara terus-menerus berubah oleh karena gangguan [[Matahari|surya]] dan planet.
Bersama Lysithea, Jupiter untuk saat ini diketahui memiliki [[Satelit Jupiter|{{jup-moon}} satelit]].
