Daimyô yashiki were Edo period mansions maintained in Edo, Kyoto, and other major cities by the daimyô. As part of the sankin kôtai system, daimyô had to spend a considerable amount of time in Edo once every few years, and to maintain a household with their wives and children as hostages in Edo. Mansions were also maintained in Kyoto, Osaka, and elsewhere, serving as bases of operations for the daimyô's political and economic activities in those cities, and housing the daimyô and his retinue as they passed through on their way to/from Edo on their sankin kôtai journeys.

Originally, the Tokugawa shogunate provided mansions to the tozama daimyô, in which their wives and children would live in Edo, as hostages, as part of the sankin kôtai "alternate attendance" system. Following the extension of sankin kôtai obligations to all daimyô in 1635, the daimyô practice of maintaining a mansion in Edo became much more common, and certain aspects of their layout, design, or locations in the city became somewhat standardized. After the 1657 Meireki Fire in particular, when the city was rebuilt, daimyô rebuilt multiple mansions in different parts of the city. A given daimyô's "upper mansion" might be located within the walls or moats (Marunouchi), below the Nishi-no-maru, or in neighborhoods such as Atagoshita or Sotosakurada; his "middle mansion" might be located just inside the outermost walls of Edo castle; and his "lower mansion" would be somewhere in the outskirts of the city.

The shogunate continued, in some cases, to allocate mansions to the daimyô, but daimyô also often seized lands from peasants to build their mansions.

Many of the most prominent daimyô's mansions have since become the sites of universities, public gardens, or the like. To name some examples, Dôshisha University is based on the former site of the Satsuma han mansion in Kyoto; Tokyo University's main campus was formerly the mansion of the lords of Kaga han; the Akasaka Detached Palace was built on the former site of the mansion of the Kishû Tokugawa; and the garden of Tokugawa Yorifusa of Mito han, Kôrakuen, continues to be maintained today as a historic site & garden open to the public.
