One UI is a user interface developed by Samsung Electronics for its mobile, computing devices and TVs, including Android-based devices running Android 9 "Pie" and later. It is the successor to Samsung Experience.

Samsung designed One UI to make using larger smartphones easier and be more visually appealing. It was announced and unveiled at Samsung Developer Conference in 7 November 2018, and was updated in the Galaxy Unpacked event in 20 February 2019 alongside the Galaxy S10 series, the Galaxy Fold, the Galaxy Watch Active, the Galaxy Fit and the Galaxy Buds, since then receiving yearly upgrades.
