Dragon 2 is a class of partially reusable spacecraft developed and manufactured by American aerospace manufacturer SpaceX, primarily for flights to the International Space Station (ISS). There are two variants: Crew Dragon, a spacecraft capable of ferrying up to seven[a] crew, and Cargo Dragon, an updated replacement for the original Dragon 1. The spacecraft consists of a reuseable space capsule and an expendable trunk module. The spacecraft launches atop a Falcon 9 Block 5 rocket and the capsule returns to Earth via splashdown. Four operational Dragon 2 spacecraft have been manufactured.

Cargo Dragon supplies cargo to the ISS under a Commercial Resupply Services-2 contract with NASA. The first flight of Dragon 2 in a cargo configuration launched in December 2020. It shares this duty with Northrop Grumman Innovation Systems' Cygnus spacecraft, and Sierra Nevada Corporation's Dream Chaser spacecraft is expected to join them no earlier than June 2022.

As of 2021, Crew Dragon is the only U.S. human-rated orbital transport spacecraft, the only reusable crewed spacecraft and the only reusable cargo spacecraft currently in operation. Its primary role is to transport crews to and from the ISS under NASA's Commercial Crew Program, succeeding the crew orbital transportation capabilities of the Space Shuttle which retired from service in 2011. No earlier than June 2022 it will be joined by Boeing Starliner in this role. Crew Dragon is also used for non-docking orbital space tourism, and is expected to be used to shuttle tourists to and from Axiom Space's planned space station.
