The Times Square Ball is a time ball located in New York City's Times Square. Located on the roof of One Times Square, the ball is a prominent part of a New Year's Eve celebration in Times Square commonly referred to as the ball drop, where the ball descends down a specially designed flagpole, beginning at 11:59:00 p.m. ET, and resting at midnight to signal the start of the new year. In recent years, the ball drop has been preceded by live entertainment, including performances by musicians. Over 1,000,000 people from around the world attend.

A time ball or timeball is a time-signalling device. It consists of a large, painted wooden or metal ball that is dropped at a predetermined time, principally to enable navigators aboard ships offshore to verify the setting of their marine chronometers. Accurate timekeeping is essential to the determination of longitude at sea.
