DD-WRT is Linux-based firmware for wireless routers and access points. Originally designed for the Linksys WRT54G series, it now runs on a wide variety of models. DD-WRT is one of a handful of third-party firmware projects designed to replace manufacturer's original firmware with custom firmware offering additional features or functionality.

Sebastian Gottschall, a.k.a. "BrainSlayer", is the founder and primary maintainer of the DD-WRT project. The letters "DD" in the project name are the German license-plate letters for vehicles from Dresden, where the development team lived. The remainder of the name was taken from the Linksys WRT54G model router, a home router popular in 2002–2004. "WRT", also used by the OpenWrt router firmware project, comes from the generic abbreviation for "Wireless Receiver / Transmitter", which may have been the original Linksys meaning.
Buffalo Technology and other companies have shipped routers with factory-installed, customized versions of DD-WRT. In January 2016, Linksys started to offer DD-WRT firmware for their routers.
Among the standard features common to all versions of DD-WRT are: access control, bandwidth monitoring, quality of service, WPA/WPA2 (personal and enterprise), the iptables firewall, Universal Plug and Play, Wake-on-LAN, Dynamic DNS, AnchorFree VPN, wireless access point configuration, multiple SSIDs, overclocking, transmission power control, and the ability to link routers. A telnet daemon is also standard. A few examples of optional features are a wireless distribution system and support for RADIUS and XLink Kai networks. DD-WRT's support for OpenVPN, WireGuard enables both protocols to pass all network traffic through a virtual private network.
