What is the full first and last name of Nancy's friend "Barb" in "Stranger Things"?

Nancy's friend "Barb" in "Stranger Things" is Barbara Holland. She is Nancy Wheeler's fiercely loyal best friend, portrayed by Shannon Purser, and her disappearance becomes one of the first major mysteries of the series.

Barb is introduced as more cautious and responsible than Nancy. She worries that Nancy's romance with Steve Harrington is pulling her away from their friendship, but she still accompanies Nancy to Steve's house for a party. After cutting her hand on the diving-board ladder, Barb sits alone beside the pool, where the Demogorgon attacks and drags her into the Upside Down.

A common mix-up is assuming Barb's surname is Wheeler because she is closely associated with Nancy. It is Holland: her parents are Marsha and her father, whose name is not central to the story. Barb's fate is later confirmed, and Nancy and journalist Murray Bauman investigate her disappearance. The public campaign demanding justice for Barb helped make the character a notable fan favorite, even though she appears primarily in season 1.
