Westfield was founded on May 6, 1834, by North Carolina Quakers Asa Bales, Ambrose Osborne and Simon Moon. It is believed that the town was planned as a stop on the Underground Railroad with many families of the Religious Society of Friends and the Wesleyan Methodist Church supporting the cause. When the laws against aiding escaped slaves were made harsher, part of the Westfield Quaker Friends Meeting House split into the Anti-Slavery Friends meeting.
Westfield was incorporated as a town in 1849.
On January 1, 2008, Westfield was incorporated as a city, and Andy Cook was sworn in as mayor. With recent annexations in southern Washington Township and rapid population growth in areas previously within the town limits, the city population in 2010 (30,068) was more than triple that of 2000 (9,293). Because of the growing size of the city, officials are planning a major revitalization of city’s downtown. New additions to downtown Westfield are expected to include a new library and city hall.
