Carlos Modesto "Botong" Villaluz Francisco (November 4, 1912 – March 31, 1969) was a Filipino muralist from Angono, Rizal.

He was one of the first Filipino modernists along with Galo Ocampo and Victorio C. Edades who broke away from Fernando Amorsolo's romanticism of Philippine scenes.

According to restorer Helmuth Josef Zotter, Francisco's art "is a prime example of linear painting where lines and contours appear like cutouts.

"[2] Francisco served as the production designer for the 1961 film adaptation of José Rizal's Noli Me Tángere.

His great works include portrayals of the Blood Compact, First Mass at Limasawa, The Martyrdom of Rizal, Bayanihan, Magpupukot, Fiesta, Bayanihan sa Bukid, Sandugo, Portrait of Purita, The Invasion of Limahong, Serenade, and Muslim Betrothal.
