The Unnamed is the second novel by American novelist Joshua Ferris, published in 2010.

The story begins in New York City where Tim Farnsworth, a successful trial attorney and partner in a law firm, apparently with everything going for him, happily married with a teenage daughter, is struck by an uncontrollable urge to walk, and keep walking.

He seeks medical and psychiatric help but his illness, which comes in episodes normally months apart, cannot be explained.

He tries to keep his job and family together but this becomes increasingly difficult, until in the end he walks out on both.

[1] In March/April 2010 issue of Bookmarks, the book received 2.5 out of 5 stars, with the critical summary saying, "Ferris’s intentions are as vague and elusive as the diagnosis for Tim’s baffling illness".
