Rey Mudjahid Ponce Millan (born 8 July 1974) better known as Kublai Millan or Kublai is a Filipino painter, sculptor, curator, and cultural mover from Mindanao. He is known for his monumental sculptures, his colorful paintings, and his culture and arts community engagements.

One of Mindanao's most prolific and influential creatives, he is the founder of Mindanao Art, the largest art event in Mindanao (and one of the largest in the Philippines). Among his most recognizable monuments are the Durian Monument in the Francisco Bangoy International Airport, sculptures at People's Park in Davao City, Christ the King Sculptures in Tagum City and the Agong House in Kapatagan, Digos City.

Kublai was born in Cotabato City, but grew up in Davao City. He is of Ilocano Settler stock. His paternal grandfather, Simeon F. Millan, was one of the two editors of the 1952 Cotabato Guidebook (a major source in Mindanao historiography). His father, Rey Ernesto Millan, is a leading mover in the bamboo industry.

He studied Fine Arts at the University of the Philippines Diliman.

After graduating, he returned to Davao City, painting and sculpting about subjects relating to the culture of his home island. Mindanao has been the dominant subject matter of his art.

Kublai started his career when he made all the artworks both inside and outside of his family's hotel Ponce Suites in Davao City, which is managed by his mother. He has since produced more public monuments and murals, and along the way his paintings have gained the attention of collectors.

In 2010, he was commissioned to make the Nativity Scene at St. Peter's Square in the Vatican, the first non-Italian artist to be thus commissioned.

In 2017 Davao City conferred him with the Datu Bago Award, and in 2022 he was given the Gador Award by the Cultural Center of the Philippines for his work in promoting Mindanao's culture and arts.
