Which character is played by Ross Partridge in "Stranger Things"?

Ross Partridge plays Lonnie Byers in Stranger Things.

Lonnie Byers is the estranged father of Jonathan and Will Byers and the former husband of Joyce Byers. The character appears in the first season as someone whose absence has left a painful mark on the family. Lonnie lives away from Hawkins and is portrayed as unreliable and primarily interested in his own concerns.

When Joyce and Jonathan visit Lonnie while searching for Will, he initially claims that Will is dead and suggests that Joyce should accept the situation. His behavior sharply contrasts with Joyce's determination to keep searching, helping establish the family's emotional history and the seriousness of the crisis.

Ross Partridge is an American actor and filmmaker. His performance as Lonnie is a supporting role rather than one of the show's central supernatural parts, which can make the character easy to confuse with other adult figures in the series. Lonnie is not Jim Hopper, Dr. Martin Brenner, or Bob Newby; he is specifically the Byers children's biological father.
