Clodualdo del Mundo Sr. (September 11, 1911 – October 5, 1977) was a Filipino novelist, playwright, essayist, short story writer, journalist, screenwriter, teacher, critic.
His parents were Mariano del Mundo, a sculptor from Bocaue, Bulacan; and Remigia Legaspi of Sampaloc, Manila.
He provided an active voice in the name of the national language when he became a member of "Taliba ng Inang Wika" (TANIW) in 1955, and its president from 1967 to 1972.
A small space in Liwayway was reserved for del Mundo's "Makabagong Tanaga", and he produced a total of 283 of these short poems.
This long collaboration produced many memorable works – from social drama, like Malvarosa and Kadenang Putik; to costume drama, like Kapitan Bagwis and Pitong Sagisag; to action stories like Ripleng de Rapido, Paltik, Asintado; and to science-fiction like Tuko sa Madre Kakaw and Zarex.
Also noteworthy among del Mundo's works in komiks medium was his adaptation of Jose Rizal's Noli Me Tangere.
During the height of the popularity of komiks-magazines, del Mundo and his colleagues formed an organization to oversee the komiks industry and to underscore the responsibility of this mass medium.
