The Hailu dialect (; Hailu Hakka Romanization System: hoiô liug` kiong`), also known as the Hoiluk dialect or Hailu Hakka (), is a dialect of Hakka Chinese that originated in Shanwei, Guangdong. It is also the second most common dialect of Hakka spoken in Taiwan.
The first edition of the Language Atlas of China places the Hakka dialects spoken in Haifeng and Lufeng into the XinâÂÂHui cluster () of the YueâÂÂTai subgroup () of Hakka. In the second edition, it is given its own subgroup known as the HaiâÂÂLu subgroup () separate from the YueâÂÂTai subgroup.
Chang Song-hing and Zhuang Chusheng propose that it should be grouped as the HaiâÂÂLu cluster () of the MeiâÂÂShao subgroup ().
In China, the Hailu dialect is spoken in Shanwei, Guangdong, particularly in Haifeng, Lufeng, and Luhe. As of 2012, there are around 1.18 million speakers of the dialect in these three areas.
In Taiwan, it is spoken in Hsinchu County (Xinfeng, Xinpu, Hukou, Qionglin, Hengshan, Guanxi, Beipu, Baoshan, Emei, and Zhudong), Hsinchu City (Xiangshan and Xinfeng), Taoyuan (mostly in Guanyin, Xinwu, and Yangmei; also pockets in Pingzhen, Zhongli, and Longtan), Hualien County (Ji'an, Shoufeng, Guangfu, Yuli, Ruisui, and Fenglin), and Miaoli County (Toufen, Sanwan, Nanzhuang, Xihu, Houlong, Zaoqiao, Tongxiao, and Tongluo).
