The NTT Docomo Yoyogi Building (NTTドコモ代々木ビル, Enu Tī Tī Dokomo Yoyogi Biru) is a skyscraper located in the Sendagaya district of Shibuya, Tokyo, Japan.

Despite the building's name, it is not the head office for the company, whose headquarters are located in the top floors of the Sannō Park Tower.

To commemorate NTT Docomo's 10th anniversary, a 15-meter-diameter clock was put into operation in November 2002.

A garbage separation system employed within the tower helps to reduce waste and increase the recycling rate.
