Ralink Technology, Corp. was a Wi-Fi chipset manufacturer mainly known for their WLAN chipsets. Originally founded in 2001 in Cupertino, California, Ralink moved its Headquarter to Hsinchu, Taiwan. On May 5, 2011 Ralink was bought by the Taiwanese company MediaTek.

Some of Ralink's 802.11n RT2800 chipsets have been accepted into the Wi-Fi Alliance 802.11n draft 2.0 core technology testbed. They have also been previously selected in the Wi-Fi Protected Set Up (WPS) and Wireless Multimedia Extensions Power Save (WMM-PS) testbeds. Ralink was a participant in the Wi-Fi Alliance and the IEEE 802.11 standards committees.

Ralink chipsets are used in various consumer-grade routers made by Gigabyte Technology, Linksys, D-Link, Asus and Belkin, as well as Wi-Fi adaptors for USB, PCI, ExpressCard, PC Cards and PCI Express interfaces. An example of an adapter is the Nintendo Wi-Fi USB Connector which uses the Ralink's RT2570 chipset to allow Nintendo DSs and Wiis to connect to the Internet via a home computer.
