Franz Sigel (November 18, 1824 – August 21, 1902) was a German military officer and immigrant to the United States who was a teacher, newspaperman, politician, and served as a Union general in the American Civil War.

Sigel resigned his commission on May 4, 1865, and worked as a journalist in Baltimore, and as a newspaper editor in New York City. He filled a variety of political positions there, both as a Democrat and a Republican. In 1887, President Grover Cleveland appointed him pension agent for the city of New York. Franz Sigel died in New York in 1902 and is buried there in Woodlawn Cemetery in The Bronx. There is a statue of him in Riverside Park in Manhattan and in Forest Park in St. Louis. There is also a park named for him in the Bronx, just south of the Courthouse, near Yankee Stadium. The village of Sigel, Pennsylvania, founded in 1865, was also named after him.
In 1909, his 19-year-old granddaughter Elsie Sigel, a missionary in Chinatown, was found strangled. Though it is thought that Leon Ling, a student of hers, was responsible, the case was never officially solved.
