The Samsung Galaxy S9 and S9+ are Android-based smartphones unveiled, manufactured, released and marketed by Samsung Electronics as part of the Galaxy S series. The devices were revealed at the Mobile World Congress in Barcelona on 25 February 2018, as the successors to the Galaxy S8 and S8+. It is the last Galaxy S series line to only have 4G network support, which was commercially released on 16 March 2018. It is also the last Galaxy S series line to feature an iris scanner, a variable-aperture lens, and a notification light.

The Galaxy S9 and S9+ have nearly identical features compared to the older S8 models, with the same display sizes and aspect ratio. One highly regarded change to distinguish between the models is the location of the fingerprint sensor. While the S8's sensor is found beside the camera, the S9's is directly underneath it, similar to the A series. Most notably, the S9 line features several camera improvements over the S8.
