Louis Francis Haffen[1] (November 6, 1854 – December 25, 1935) was an American engineer and politician who was the first Bronx Borough President.

They had five sons, Mathias, Louis Jr., Henry, John and Thomas, and a daughter, Beatrice W. Haffen Havender.

He died on Christmas Day, 1935 of reported heart problems and is interred at Woodlawn Cemetery in The Bronx.
