Suluan is an island barangay in the Philippines, in the municipality of Guiuan, Eastern Samar.

On March 16, 1521, after 98 days of crossing the Pacific Ocean, Magellan's voyage dropped anchor on the island of Homonhon ("Humunu" in Pigafetta's account).

They returned on March 22 with other supplies to trade, including more coconuts, palm liquor, sweet oranges, and a rooster.

Magellan and his crew spent a week interacting with the tattooed locals of Suluan, whom they described "pleasant and conversable," before they left for Limasawa.

On October 17, 1944, the 6th Ranger Battalion landed on Dinagat, Homonhon and Suluan, securing the entrance to Leyte Gulf for General Douglas MacArthur's forces.
