Yongfeng Warehouse Site, Archaeological warehouse remains in Ningbo, China.

The Yongfeng Warehouse Site in Ningbo's Haishu District preserves the foundations of a large rectangular building from the Yuan dynasty, measuring 56.3 by 16.7 metres, with walls supported by square stone blocks holding wooden posts. Excavations in 2001 and 2002 uncovered superimposed remains of Southern Song, Yuan and Ming warehouses, including brick-paved courtyards, roads, wells and drainage channels. The site is now a park with a full-scale replica of the Yuan structure.

The site gained national protection status in 2006 and preserves evidence of maritime trade and commercial activities spanning multiple dynasties. The archaeological discoveries document Ningbo's development as a major trading port throughout different historical periods.

The site's name changed with each dynasty: Changping Granary under the Southern Song, Yongfeng Warehouse under the Yuan, and Hongji Granary from 1370 under the Ming. Yuan records state Yongfeng stored confiscated goods and fines along with salt and tea tax revenues. Excavated ceramics from kilns such as Longquan, Ding and Jun match wares found on the Korean Sinan shipwreck, a vessel linked to Ningbo.

The site lies east of Ningbo's Drum Tower, within the old Tang-Song sub-city area. Since 2008 the excavated ground has been backfilled and covered by a park with a full-scale replica of the remains; raised walkways mark the visiting route. The park, Ningbo's first archaeological park, opened to the public in March 2009 and had its signage improved in 2017. The original finds are kept mostly in the Ningbo Museum.

Excavations in 2001 uncovered Tang-dynasty Persian blue-glazed pottery in the No. 1 building foundation, evidence of Ningbo's overseas trade. A Tang bronze seal inscribed "Seal of the Stationery Studio" in raised characters also came from the site. Ceramics matching those from the Korean Sinan shipwreck, a vessel carrying "Qingyuan Circuit" weights, were found here.
