Drvenik Veli is a Croatian island in the Adriatic Sea. It is situated in the middle of the Dalmatian archipelago, northwest of à  olta, from the mainland. Its area is . The highest peak is 178 metres high. The only settlement on the island is the near-eponymous village of Drvenik Veliki () with a population of 150 (2011 census).
The island was first inhabited in the 15th or 16th century. The main industries on the island are agriculture, fishing and tourism. The coast of the island is mainly rocky, but also has a few famous sand and pebble beaches like Krknjaà ¡i and Kokoà ¡inje.
Since ancient times, the island has been known by its Romanized name, Zirona. The name Zirona likely originated from the Illyrian root "gà ³er" meaning "forest", possibly because of the island's once dense woodlands. In Croatian documents from the 13th century, the island is mentioned as Girona, Gerona or Giruna. Some suggest that the name Girona might have Greek origins, derived from the noun "gyrona" meaning "rounded object", a notion supported by the island's somewhat rounded morphology. The Croatian name Drvenik ("veli" means "large" in Croatian) finds its origin in the Croatian word "drvo", meaning "wood", establishing a link either to its Illyrian roots, according to some, or to the town of Drvenik near Makarska, from which a significant portion of its population migrated in the 17th century.
