Mulholland is primarily a surname of Irish origin, anglicized from Ó Maolchalann , meaning "descendant of Maolchalann" or "chief of the calends" (referring to the first day of the month in ancient calendars).
It is also the name of Mulholland Drive , a famous 21-mile scenic road in the Santa Monica Mountains above Los Angeles, named after civil engineer William Mulholland (1855–1935), who designed the Los Angeles aqueduct.
The term gained cultural fame through David Lynch's 2001 surreal film Mulholland Drive , which explores Hollywood dreams and nightmares along this iconic, winding route known for its stunning views and celebrity homes.
