In which US city is the famous New Year's Eve ball drop held?

The famous New Year’s Eve ball drop is held in New York City, specifically in Times Square.

The Times Square Ball descends from the roof of One Times Square during the final minute of December 31. It reaches the bottom at midnight Eastern Time, signaling the start of the new year and forming the centerpiece of New York City’s best-known New Year’s Eve celebration.

The tradition began on December 31, 1907, welcoming 1908. New York Times publisher Adolph Ochs wanted a spectacular event for the newspaper’s headquarters, and sign designer Artkraft Strauss built the first ball from wood and iron. It replaced earlier fireworks displays after concerns about launching fireworks over crowds.

The drop was suspended during the wartime blackouts of 1942 and 1943, when crowds observed a moment of silence instead. Today’s event includes musical performances, confetti, fireworks, and a crystal-covered illuminated ball. Other American cities hold their own object drops, but the globally famous ball drop is the one in Times Square.
