Naniwa Nagara-Toyosaki Palace (難波長柄豊碕宮, Naniwa-no-Nagara-no-Toyosaki-no-miya), is a historical palace which was located in present-day central Osaka city, Japan. The palace of this period is also sometimes referred to as the Former Naniwa Palace (前期難波宮, zenki-Naniwa-no-miya), to contrast it with the (Latter) Naniwa Palace built in the same location in 744 AD.

Construction of the palace was completed in 652 AD. The palace stood for 34 years before being destroyed by fire in 686 AD.
