Zhe Yun Wong, better known as Mr. Wong, is an enforcer of the Empire Bay Triads, and the tertiary antagonist of the second half of Mafia II.

After Henry Tomasino made a heroin deal with him, Mr Wong found out from his contact in the Federal Bureau of Narcotics that Henry was an informant. Following this information, Mr Wong ordered the Tongs to hack Henry to death.

As retaliation, Vito and Joe followed Mr. Wong to the Red Dragon Restaurant and massacred several Tongs. After an interrogation with Mr. Wong, Joe executed Mr. Wong.
