Tien Lei (simplified Chinese: 田垒; traditional Chinese: 田壘; pinyin: Tián Lěi; born June 1, 1983, in Kaohsiung) is a Taiwanese professional basketball player.

Considered one of the most talented offensive players in Taiwan, Tien has won multiple scoring and rebounding champions of the Super Basketball League (SBL) there, while helping his team, the Dacin Tigers, to its first championship title in franchise history in 2009.

Since his national team debut at the FIBA Asia Championship 2001, Tien has served as starting power forward for the Chinese Taipei men's national basketball team.

At the 2009 FIBA Asia Championship, he helped Chinese Taipei to a fifth-place finish, the team's best record in the tournament since the turn of the century, while averaging 10.6 points and 5.8 rebounds per game.
