The announcement was made at the same time Carnival confirmed all 22 of its US-based ships will be back in guest operations by March 2022.
Christine Duffy, president of Carnival Cruise Line, said the ship will bring an "entirely new" cruise experience for its guests.
"Carnival was the first cruise line to offer year-round cruising from Galveston in 2000, and we have continued to grow our presence and support of the Port of Galveston’s expansion, so we are thrilled to bring our brand-new Carnival Jubilee to Texas and the greater south-west region," she added.
Jubilee will be the third in the Excel-class for Carnival, joining sisters Mardi Gras, sailing from Port Canaveral since earlier this year, and Carnival Celebration, which will be delivered in late 2022 and based in Miami.
The vessel will arrive at 182,800 gross tonnes with a capacity of more than 5,400 guests and 1,700 crew and will offer seven-day western Caribbean sailings. Itineraries will go on sale in early 2022.
