All Fours is a 2024 novel by acclaimed artist and filmmaker Miranda July. The story follows a semi-famous 45-year-old artist who embarks on a solo cross-country road trip from Los Angeles to New York. However, she only makes it as far as a nondescript motel thirty minutes from her home, where she begins a transformative journey of self-discovery. The novel explores themes of perimenopause, female desire, the complexities of long-term marriage, and the radical reinvention of one's life.

The novel has been widely discussed for its frank and irreverent portrayal of middle age and female sexuality. Critics have praised July's unique voice, comic timing, and her ability to push the boundaries of domestic fiction. It has been described as both a 'divisive' and 'essential' read for its honest look at the physical and emotional shifts of perimenopause.
