Jiangyin dialect (江阴话) is a Northern Wu Chinese dialect spoken in the city of Jiangyin in Jiangsu province. Jiangyin dialect is a member of the Wu Chinese Taihu Wu family of dialects, which means the inhabitants speak a dialect similar to that of nearby Wuxi, Changzhou, Suzhou, and Shanghai. Jiangyin dialect itself is of the Piling variety, related to the Changzhou dialect. Jiangyin dialect has the highest degree of mutual intelligibility with the dialects of the closest neighboring cities of Changzhou and Wuxi but also has a fairly large degree of mutual intelligibility with the dialects of nearby Suzhou and Shanghai. As one travels south towards Wuxi away from the urban center of Jiangyin, Jiangyin dialect gradually becomes more and more closer sounding to the Wuxi dialect.
A book called A collection of Jiangyin dialect has been published.
