Pennsylvania Dutch English is a dialect of English that has been influenced by the Pennsylvania Dutch language. It is largely spoken in South Central Pennsylvania, both by people who are monolingual in English and bilingual in Pennsylvania Dutch and English. The dialect has been dying out, as non-Amish younger Pennsylvania Germans tend to speak General American English.

Very few non-Amish members of these people can speak the Pennsylvania German language, although most know some words and phrases. The World War II generation of the mid-20th century was the last generation in which Pennsylvania Dutch was widely spoken outside the Amish and Old Order Mennonite communities.
