John Henry Hoffecker (September 12, 1827 – June 16, 1900) was an American engineer and politician from Smyrna in Kent County, Delaware.

However, enough votes went to the regular (Anti-Addicks) Republican candidate, John C. Higgins, that Democrat Ebe W. Tunnell was elected.

On June 16, 1900, during a visit home from the 1900 Republican National Convention in Philadelphia, Hoffecker suffered a stroke and died.

His son, Walter O. Hoffecker, was elected to finish his term in the U.S. House.

His home, Ivy Dale Farm, was listed on the National Register of Historic Places in 1973.
