Lupin is the surname of a wizarding family, though they have Muggle as well as magical heritage. They are related to the Tonks family, and thus distantly to the Black, Malfoy, and Potter families. The Lupins supported the Order of the Phoenix during the First and Second Wizarding Wars. Members include Remus Lupin, Nymphadora Lupin, Ted Lupin, and Remus' parents, Lyall and Hope Lupin.
|Lyall Lupin||Father of Remus; a Ministry of Magic employee who banished the Screaming Bogey of Strathtully; once offended the werewolf Fenrir Greyback|
|Hope Lupin (née Howell)||Mother of Remus|
|Remus Lupin||A werewolf and member of the Order of the Phoenix|

|Teddy Lupin||Orphaned son of Remus and Nymphadora; a Metamorphmagus like his mother|

Lupin is derived from the Latin word lupus, meaning "wolf". Lupin or lupine is also the name of a flower, and the latter is an English adjective meaning "wolflike". This alludes to the lycanthropy in the family.
