Lucius Nathan Littauer (January 20, 1859 – March 2, 1944) was an American politician, businessman, and college football coach.

Littauer graduated from Harvard University in 1878 and was the school's first head football coach, guiding the Crimson to a record of 6–1–1 in 1881.

[2][3] Returning to Gloversville, Littauer entered his father's glove making business and went on to become an officer and director of many commercial and financial institutions.

On February 4, 1914, Littauer and his brother William were convicted of smuggling and conspiracy to defraud after admitting to having imported valuable jewels from Venice worth in excess of $40,000 without paying the necessary duty.

In his decision, Thomas stressed that Littauer's high standing served to aggravate the crime: "For an ex-congressman so far to forget his oath taken five times and knowing so well the provisions of the law he helped to frame seems to be incomprehensible.
