The Samsung Galaxy S II (also unofficially known as the Samsung Galaxy S2) is a touchscreen-enabled, slate-format Android smartphone developed and marketed by Samsung Electronics, as the second smartphone of the Samsung Galaxy S series. It has additional software features, expanded hardware, and a redesigned physique compared to its predecessor, the Samsung Galaxy S. The S II was launched with 2.3.4 "Gingerbread", with updates to Android 4.1.2 "Jelly Bean".

Samsung unveiled the S II on 13 February 2011 at the Mobile World Congress (MWC) in Barcelona. It was one of the slimmest smartphones of the time, mostly 8.49 mm thick, except for two small bulges which take the maximum thickness of the phone to 9.91 mm. The Galaxy S II has a 1.2 GHz dual-core "Exynos" system on a chip (SoC) processor, 1 GB of RAM, a 10.8 cm (4.3 in) WVGA Super AMOLED Plus screen display and an 8-megapixel camera with flash and 1080p full high definition video recording. It is one of the first devices to offer a Mobile High-definition Link (MHL), which allows up to 1080p uncompressed video output to an MHL enabled TV or to an MHL to HDMI adapter, while charging the device at the same time. USB On-The-Go is supported.

The user-replaceable battery gives up to ten hours of heavy usage, or two days of lighter usage. According to Samsung, the Galaxy S II is capable of providing 9 hours of talk time on 3G and 18.3 hours on 2G.

The Galaxy S II was popular and a huge success both critically and commercially, selling 3 million units within its first 55 days on the market. It was succeeded by the Samsung Galaxy S III in May 2012.
