Infinity Lake Spaceport was a spaceport located on Infinity Lake on the planet Nepenthe. It offered a weekly passenger service, though independent operators were rare.

In 2399, William T. Riker and Deanna Troi suggested to Jean-Luc Picard and Soji Asha that they could seek transportation off-world at Infinity Lake Spaceport, if they were willing to wait. (PIC: "Nepenthe")
