If she weren't an actress, Keeley would've wanted to be a neurosurgeon so she could have a real difference in someone else's life. Another more realistic alternative job she would have liked is a teacher.
One of her favorite books is William Golding's Lord of the Flies.
While she studied at Sylvia Young stage school, Keeley lived with ex-Spice Girl and school mate Emma Bunton.
When she filmed the bedroom scene where she had to show her bottom in A Cock and Bull Story (2005), Keeley was eight months pregnant so she chose a body double to do the nude scene.

Keeley voice-acted the character Maid Marion in Robin Hood's Quest and Quest for Aladdin's Treasure, both released in 2007. She also provided the voice of Lara Croft in Tomb Raider: Legend (2006), Tomb Raider: Anniversary (2007), and Tomb Raider: Underworld (2008).

In interviews to Diva magazine and The Radio Times in 2002, she stated that she was bisexual. In 2009, she explained that she was misquoted when what she actually said was, "everybody is probably perfectly capable of finding somebody of the same sex attractive". Keeley claimed she has never had any lesbian relationships.
In the 2007 comedy Death at a Funeral, she played onscreen wife to real-life husband Matthew Macfadyen.
From December 2001 to 2004, Keeley was married to entrepreneur Spencer McCallum, with whom she had a son, Myles (b. 2000).

Keeley Hawes: I'm very maternal, and there's a really lovely thing you can do where you look after a disabled child for a while to give their parents some respite.
Keeley Hawes: (on watching her figure) Life is simply too short to think about everything you put in your mouth, and it's not good for children to see you picking over bits of salad.
Keeley Hawes: (on wanting to become famous; in a 2000 interview) I'm ambitious, but I'm not ruthless in any way. It was never something that I was hungry for. I don't come from that. I come from something so normal. I know that I can always do something else besides act. It's not going to drive me crazy.
Keeley Hawes: My God, I'd be the worst, most depressed person if I stayed at home every day of the year. It would be awful for me and my family. I've nothing against stay-at-home mums, but I would become unbearable, such a horrible, miserable bitch.
Keeley Hawes: I'm not self-conscious about my body, but I think I will keep it covered up after having three children. There comes a time when you have to say, 'Hmm, that's it, I think I'll save it for indoors.'
Keeley Hawes: I think that it's pointless staying in a loveless marriage. I wasn't in a loveless marriage but if you're not happy, then that reflects - doesn't it? - on your children. Happy grown-ups make for happy children.
Keeley Hawes: (on what she clings on from childhood) I think I've still got quite a childish sense of humour, and I'm quite giggly. I've been like that since I was quite little. I'm the worst for corpsing. I should make a mint in outtakes.
Keeley Hawes: 'Complicity' is risque, but I'm not bothered by such things. I watched Robocop the other night and it was full of gratuitous violence. I would rather see gratuitous sex.
Keeley Hawes: I was sent the DVD of me in ShakespeaRe-Told: Macbeth, and there was this big, dramatic moment and I was thinking 'this is looking good', when Myles came in and said, 'Oh Mummy, when are you going to do something good like Madagascar'?
Keeley Hawes: (in a 2008 interview) I've been really lucky with my career so far. I haven't been pigeon-holed, which sometimes happens to actors. The exciting thing is having something that you'd have never thought of drop on your mat and thinking 'Oh God, I'd love to do this'. But I can't complain - I'm even lucky enough to have done my pocket version of Lady Macbeth!
Keeley Hawes: We now think low-slung hipsters are very sexy but actually back then it was all about the waist. It took a while to get my head around the high waists – I was thinking, 'Gosh, this makes my bum look really long!
