The Pixel 2 and Pixel 2 XL are a pair of Android smartphones designed, developed, and marketed by Google as part of the Google Pixel product line. They collectively serve as the successors to the Pixel and Pixel XL.

They were officially announced on October 4, 2017 at the Made by Google event and released in the United States on October 19. They were succeeded by the Pixel 3 and Pixel 3 XL On October 9, 2018. Both models reached their planned end-of-life date in October 2020; their final security update was released in December 2020.

In early March 2017, Google's Rick Osterloh confirmed that they would bring a "next-gen" Pixel smartphone later that year. He stated it would "stay premium" and that there would be no "cheap Pixel".

Google originally intended to use HTC to manufacture both their 2017 flagships, but later shifted to LG to manufacture the bigger Pixel 2 XL. The unreleased device that was supposed to be the Pixel 2 XL under the codename "Muskie", was later re-developed by HTC into the HTC U11+.

The Google Pixel 2 and Pixel 2 XL were carried in the United States by Verizon and Project Fi. On October 4, 2018, Verizon stopped selling the Pixel 2.

The back of the Pixel 2 and Pixel 2 XL are made from aluminum with a thin "premium coating" of plastic and has a top section made from glass to provide wireless transmissivity. Unlike the original Pixel XL, which was simply an enlarged version of the Pixel design with no other changes, the Pixel 2 XL's external design differs from its smaller sibling, employing a taller 2:1 P-OLED display (marketed as 18:9) instead of the Pixel 2's 16:9 AMOLED.

The Pixel 2 and Pixel 2 XL are both powered by the Qualcomm Snapdragon 835, coupled with 4 GB LPDDR4X RAM. They both come in storage options of 64 or 128 GB.

The Pixel 2 has a 5-inch (130 mm) 16:9 1080p (1920 × 1080) AMOLED display panel with a pixel density of 441 ppi, while the Pixel 2 XL comes with a 6-inch (150 mm) 2:1 1440p (2880 × 1440) P-OLED display panel with a pixel density of 538 ppi.
