John Williams Stoddard (October 1, 1837 – September 18, 1917) was an American manufacturer of agricultural implements and automobile pioneer.

That business was continued for three or four years when it was enlarged, and the manufacture of varnishes was added, the firm also dealing by wholesale in paints, oils, window glass, etc., under the name of Stoddard & Company.

The chief implements made by the Stoddard Manufacturing Company were mowers, hay rakes, press drills, and disc harrows.

In the mid-1890s, they diversified to take advantage of the bicycle craze then sweeping the United States, manufacturing the Tiger (and Tigress), Cygnet, and Tempest lines of bikes until 1898.

In 1903, John W. Stoddard and his son Charles (1866–1921), having made a fortune in agricultural equipment, turned to making automobiles.

It became the second largest employer in Dayton, second only to Barney & Smith, occupying the 68,000-square-foot (6,300 m2) plant at Third and McDonough Streets that had been built for the agricultural implements forerunner in 1871.

The Queen Anne-style Stoddard mansion stood on Grafton Hill overlooking the Great Miami River and the city of Dayton.

The John W. Stoddard family, including his parents, brothers and children, are interred at Woodland Cemetery, Dayton, Ohio.
