Ronghua Dam ({{zh|t=榮華大壩|hp=Rónghuá Dàbà|w=Jung²-hua² Ta⁴-pa⁴}}) is a concrete arch dam crossing the Dahan River, a tributary to the Tamsui River, in Fuxing District, Taoyuan City, Taiwan.[http://www.everysingleplace.com/features/4652140-jung-hua-ta-pa-lien-chiang-hsien-taiwan-information Jung-hua Ta-pa (dam), Taiwan]{{dead link|date=February 2025|bot=medic}}{{cbignore|bot=medic}}.

The dam was started in December 1978 and finished in June 1984.[http://www.wranb.gov.tw/ct.asp?xItem=1896&ctNode=623&mp=6 Junghua Dam], [http://www.wranb.gov.tw/mp.asp?mp=6 Northern Region Water Resources Office], [http://www.wra.gov.tw/ Water Resources Agency], Ministry of Economic Affairs, Taiwan. The cost was NT$1.83 billion.

The Ronghua Dam is within the catchment area of the Shihmen Reservoir, 27 kilometers upstream of the Shihmen Dam in the Dahan River gorge. The dam's main function is to prevent sand from moving downstream and building up as silt in the Shimen Reservoir. It also serves as a diversion point for sending water to a 40,000 kilowatt hydroelectric plant located {{convert|6|km|mi}} downstream.

As of 2012, the dam has no effective storage capacity, as almost its entire reservoir has been filled by sediment.
