The "Empire" star was joined by his real-life wife Mira Park and their two young children at the ceremony, where the actor was overcome with emotion as he gazed at his name on the sidewalk.
The 50-year-old, who recently announced plans to retire from acting following "Empire"'s current final season, said, "One of the things I do want to say, is because of all of you, my fans, my friends... I will never be forgotten."
"Because my name is written in stone in Hollywood, as long as there is a Hollywood Boulevard, Terrence Howard will still stand. I just want to say thank you, thank you, thank you for all of this."
Howard's star is the Walk of Fame's 2,674th.
