Alex Niño (born May 1, 1940) is a Filipino comics artist best known for his work for the American publishers DC Comics, Marvel Comics, and Warren Publishing, and in Heavy Metal magazine.

Alex Niño was born May 1, 1940, in Tarlac, Central Luzon, the Philippines, the son of a professional photographer. Niño studied medicine briefly at the University of Manila before leaving in 1959 to pursue his childhood goal of becoming a comics artist. In 1965, after studying under artist Jess Jodloman, Niño collaborated with Clodualdo del Mundo Sr. to create the feature "Kilabot Ng Persia" ("The Terror of Persia") for Pilipino Komiks. Niño and Marcelo B. Isidro later created the feature "Dinoceras" for Redondo Komiks. Other Valry Philippine work includes the series Gruaga - The Fifth Corner of the World for Pioneer Komiks; the feature "Mga Matang Nagliliyab" ("The Eyes that Glow in the Dark") with Isidro for Alcala Komiks; and for PSG Publications, stories of Bruhilda Witch, which were adapted into movies.

Niño was among the vanguard of Philippine comics artists — including Alfredo Alcala, Nestor Redondo, and Gerry Talaoc — recruited for American comic books by DC Comics editor Joe Orlando and publisher Carmine Infantino in 1971, following the success of the pioneering Tony DeZuniga. Niño's earliest U.S. comics credit is penciling and inking the nine-page story "To Die for Magda" in DC Comics' House of Mystery #204 (July 1972) written by Carl Wessler. Niño was soon contributing regularly to such other DC supernatural anthologies as companion title House of Secrets and Forbidden Tales of Dark Mansion, Secrets of Sinister House, Weird War Tales, Weird Mystery Tales, and The Witching Hour. He also drew the jungle-adventure feature "Korak" in some issues of DC's Tarzan. Except for one story for Gold Key Comics' Mystery Comics Digest #17 (May 1974), Niño, who moved to the U.S. in 1974, drew comics exclusively for DC through the beginning of 1975.

With writer-editor Robert Kanigher, Niño created DC's 19th-century Caribbean-pirate protagonist Captain Fear in Adventure Comics #425 (Dec. 1972). Niño and writer Jack Oleck created the science-fiction feature "Space Voyagers" in Rima, the Jungle Girl #1 (May 1974).

In 1973–1974, Niño worked for Pendulum Press, illustrating comic book adaptations of the classic literary works The Time Machine, Moby-Dick, The Three Musketeers, The Invisible Man, and The War of the Worlds. In 1976, several of these stories were reprinted, with added color, by Marvel Comics in their Marvel Classics Comics line.

After drawing some house ads and a frontispiece for two of Marvel Comics' black-and-white comics magazines, Niño teamed with writer-editor Roy Thomas on a 17-page adaptation of the Harlan Ellison short story "'Repent, Harlequin!' Said the Ticktockman" in the black-and-white Unknown Worlds of Science Fiction #3 (May 1975). This led to a 30-page Conan the Barbarian tale, "People of the Dark" in The Savage Sword of Conan #6 (June 1975), also with Thomas, and a 23-page adaptation of the Michael Moorcock novel Behold the Man, with writer Doug Moench in Unknown Worlds of Science Fiction #6 (Nov. 1975).

Niño signed a contract with Ralph Bakshi to work on the film Wizards, and was granted a work visa, but was unable to gain permission from the Philippine government in order to leave for the United States until two months afterward. By the time he had arrived in the U.S., not only had the film's animation been completed, but Niño's visa did not allow him to submit freelance work on any other projects.

Niño did little else for Marvel's color comics, inking two issues of the Luke Cage series Power Man and a "Weirdworld" story in Marvel Premiere #38 (Sept. 1977).
