Grand Piece Online is the online seafaring Roblox game inspired by the One Piece anime and manga series. GPO gives players free reign to explore a wonder-filled waterworld that should be very familiar to those who follow the adventures of Luffy and his ragtag crew.
Of course, sailing the high seas is a lot more fun when you know where you’re going! In this guide, we’ll show you the entire GPO map, including full maps of both sea regions. Knowing where all the islands are will allow you to set a clear destination and travel with purpose. So strap on your favorite eyepatch and let’s dive right in, shall we?

Grand Piece Online maps
The overworld of Grand Piece online is separated into two main regions: the First Sea (also known as the Sea of Phoeyu) and the Second Sea (or the New World). Below, you’ll find maps for both regions, as well as a full list of their islands, the recommended level you should be at when visiting them, and what items you can find there.
Additionally, we’ll talk a bit about Skypiea (Land of the Sky), which is the largest inhabited zone in the First Sea.
