Joseph O'Neill is an Irish novelist and non-fiction writer.

O'Neill was born in Cork, Ireland, in 1964, and grew up in The Netherlands. He is a graduate of Girton College, Cambridge, and a barrister at the English Bar, where he practised for ten years, principally in the field of business law. He now lives in New York with his wife, Vogue editor Sally Singer, and their three sons.

O'Neill is the author of three novels, the most recent of which, Netherland, was published in May 2008 and was featured on the cover of the New York Times Book Review where it was called, "the wittiest, angriest, most exacting and most desolate work of fiction we’ve yet had about life in New York and London after the World Trade Center fell". He is also the author of a non-fiction book, Blood-Dark Track: A Family History, which was a New York Times Notable Book for 2002 and a book of the year for the Economist and the Irish Times.

O'Neill writes literary and cultural criticism, most regularly for the Atlantic Monthly.

In a New York City made phantasmagorical by the events of 9/11, Hans--a banker originally from the Netherlands--finds himself marooned among the strange occupants of the Chelsea Hotel after his English wife and son return to London. Alone and untethered, feeling lost in the country he had come to regard as home, Hans stumbles upon the vibrant New York subculture of cricket, where he revisits his lost childhood and, thanks to a friendship with a charismatic and charming Trinidadian named Chuck Ramkissoon, begins to reconnect with his life and his adopted country. Ramkissoon, a Gatsby-like figure who is part idealist and part operator, introduces Hans to an “other” New York populated by immigrants and strivers of every race and nationality. Hans is alternately seduced and instructed by Chuck’s particular brand of naivete and chutzpah--by his ability to a hold fast to a sense of American and human possibility in which Hans has come to lose faith.

Netherland gives us both a flawlessly drawn picture of a little-known New York and a story of much larger, and brilliantly achieved ambition: the grand strangeness and fading promise of 21st century America from an outsider’s vantage point, and the complicated relationship between the American dream and the particular dreamers. Most immediately, though, it is the story of one man--of a marriage foundering and recuperating in its mystery and ordinariness, of the shallows and depths of male friendship, of mourning and memory. Joseph O’Neill’s prose, in its conscientiousness and beauty, involves us utterly in the struggle for meaning that governs any single life.
