Poco (stylized as POCO), formerly known as Poco by Xiaomi is a Chinese brand owned by Xiaomi that specializes in smartphones. The Poco brand was first announced in August 2018 as a mid-range smartphone line under Xiaomi. Poco India became an independent brand on 17 January 2020, followed by its global counterpart on 24 November 2020. Poco released its first smartphone, the Pocophone F1 in August 2018.

Some phones with identical or slightly changed specifications are released in some markets as Poco, in others as Redmi; for example the Poco F7 and Redmi Turbo 4 Pro

The Poco brand was launched as a Xiaomi sub-brand in August 2018. The Poco sub-brand had a small team within Xiaomi, and chose the name Poco as it represented the team since "poco" means "a little" in Spanish and Italian. Xiaomi introduced the Pocophone F1 under the Poco branding which became a success. Poco India became an independent brand before the launch of its second device in January 2020. During the span of 3 years, the brand launched 11 devices, most of them are rebranded Redmi smartphones.

In January 2021, Poco India introduced its new mascot and slogan Made of Mad.

In October 2024, Poco announced that it will shut down its official website by 31 December 2024. The brand will instead relocate its product pages, customer, service, after-sales service, and other products and services to Xiaomi's global website under the mi.com/global/ domain.

The Android and MIUI/Xiaomi HyperOS update support may vary depending on the series model.
