Earth is the only planet known to have liquid water oceans on its surface.
That is the Earth.
The Earth is called the blue planet because when viewed from space, the majority of its surface is covered by water, giving it a blue appearance. The reflection of the oceans and atmosphere causes the planet to appear blue when seen from a distance.
There is only one planet known to have significant bodies of liquid water that cover a large portion of its surface, and that is Earth. Other planets in our solar system, like Mars and Europa, have evidence of liquid water in the past or under their surface, but not as extensive as Earth's oceans.
