{{nihongo|Sanada-shi Yakata|真田氏館|Sanada-shi Yakata}} is the remains of a fortified residence of the Sanada clan in Ueda, Nagano Prefecture, Japan. The site is believed that it was a main bastion of the Sanada clan until Sanada Masayuki moved their base to Ueda Castle in 1585.{{cite web|url=https://sightseeing.jrnets.co.jp/detail/spot/27575.html|title=真田氏館|publisher=East Japan Railway Company|language=Japanese|access-date=16 October 2021}}
