Naomi Ellen Watts (born 28 September 1968) is a British-Australian actress. She is known for her roles in Mulholland Drive, the film remakes of The Ring, King Kong, Funny Games and her Academy Award-nominated role in the film 21 Grams.

Watts was born in Shoreham, Kent, England, the daughter of Myfannwy Glennys Edwards "Miv" (née Roberts), an antiques dealer and costume and set designer, and Peter Watts, a road manager and sound engineer who worked with Pink Floyd (her father's manic laugh can be heard in "Speak to Me" and "Brain Damage" and her mother's comments can be heard in "The Great Gig in the Sky" and "Money" from The Dark Side of the Moon). Watts is pictured, in her mother's arms, with her father, brother, the band, and other crew members, in the hardback/softcover edition of drummer Nick Mason's autobiography of the band Inside Out.

Watts has one brother, Ben, a year older and now a photographer in the United States. Watts' parents separated when she was four years old, and when she was seven, her father died. Following her father's death, her mother relocated the family to Llanfawr Farm, on the Isle of Anglesey in North Wales, where they lived with Watts' maternal grandparents, Nikki and Hugh Roberts.
