Mechanic Street Cemetery is a historic colonial cemetery on Mechanic Street in Westfield, Massachusetts. The 4-acre (1.6 ha) cemetery is the city's oldest, with the oldest documented grave dating to 1683. It was used as a burying ground until the late 19th century, although its use began to decline in the middle of the century, with the advent of the popular rural cemetery movement, which was reflected in Westfield with the establishment of the new Pine Hill Cemetery in 1842.
