The Ambassadors by Henry James is a 1903 novel by Henry James, originally published as a serial in the North American Review (NAR). The novel is a dark comedy which follows the trip of protagonist Lewis Lambert Strether to Europe to bring the son of his widowed fiancée back to the family business. The novel is written in the third-person narrative from Strether's point of view.

Lewis Lambert Strether, the protagonist of the novel, is a cultured man in his fifties from the fictional town of Woollett, Massachusetts, who is dispatched to Paris to find Chad, the wayward son of his fiancée Mrs Newsome. The book is entirely told from Strether's point of view and chronicles his change from an American to a European view of things.

Strether, a middle-aged American of insignificant means, is sent to Paris by Mrs. Newsome, his wealthy fiancée. The mission he has been given is to talk her son, Chad, into returning to the family business in Woollett, Massachusetts.

The Newsome family believes that Chad might be overstaying his European tour because of an inappropriate romantic liaison, perhaps with a vulgar adventuress. The reader is given to understand, in indirect ways, that if Strether fails, his engagement to Mrs. Newsome is at risk.
