Bart Township is a township in southeastern Lancaster County, Pennsylvania, United States. At the 2020 census, the population was 3,181,^[2] up from 3,094 at the 2010 census.

Situated in a highly Amish region of Lancaster County, only 43.7% of the township's population speaks English, while 56.3% speaks an "other [than Spanish] Indo-European language"^[2] (almost entirely Pennsylvania German/German).

The name of Bart Township apparently comes from a reinterpretation of the abbreviation "Bart." for "Baronet".^[3] This abbreviation was used by former Colonial Governor Sir William Keith, Bart.^[4] After being forced out of the Governorship by Hannah Penn,^[5] Sir William Keith, Bart. won election as an Assemblyman in Philadelphia. In March 1728, Sir William Keith, Bart. left Pennsylvania in a hurry—he was running out on his debts. He left for England, never to return^[6] He abandoned his wife, Lady Keith, who is buried in Christ Church Cemetery in Philadelphia.

What is now Bart Township was part of Sadsbury, Chester County before the formation of Lancaster County.

In 1744, Sadsbury Township was split into two; the western part was organized as Bart Township and the eastern part remained Sadsbury Township. In 1854, Bart Township was split into two, with the western part organized as Eden Township, and the eastern part remaining Bart Township.^[7]

On October 2, 2006, a lone gunman, identified as Charles Carl Roberts IV, shot ten Amish schoolgirls, killing five of them, in an attack on West Nickel Mines Parochial School, an Amish one-room school in Nickel Mines, Bart Township. Roberts then shot and killed himself as police responded.
