James W. L. Slavens (August 3, 1838 – February 10, 1905) was a meat-packing businessman and politician from Missouri. He served as Mayor of Kansas City in 1877 and as mayor of Westport in 1894. He was known for starting one of the first meat-packing businesses in Kansas City.

James W. L. Slavens was born on August 3, 1838, in Putnam County, Indiana, to Sarah (née Holland) and Hiram B. Slavens. His father was a farmer and helped establish Indiana Asbury University. Slavens graduated from Indiana Asbury University in 1859.

After graduating, Slavens moved to Douglas County, Illinois. Until 1870, he was engaged in farming. He started to study law and in 1861 he joined the practice of William McKenzie in Tuscola, Illinois. Slavens joined the Union Army soon after the start of the Civil War. He was appointed as quartermaster of the 73rd Illinois. He was later detailed for duty at the subsistence department. In his last year, he joined the staff of General George H. Thomas. He was mustered out in July 1865.

In 1865, Slavens moved to Jackson County, Missouri and then Independence. He came to Kansas City in 1866. He formed a law partnership with his brother, Luther C. Slavens. He practiced law with his brother for about eight years.

In the spring of 1868, Slavens, along with E. W. Pattison and William Epperson, started a meat-packing business. Afterward, Slavens got into business with J. C. Ferguson and J. L. Nofsinger. The company operated as Ferguson, Slavens & Co. for four years. Then it was renamed as Slavens, Mansur & Co. with J. H. Mansur. In 1875, Slavens was found guilty of fraud by the Red Cloud Agency Investigative Commission after supplying 600 barrels of inferior grade pork. Slavens was excluded from future contracts with the government.

Slavens became the city treasurer of Kansas City in 1867 and served for one year. He was elected on a Republican ticket as Mayor of Kansas City in 1877. He later became mayor of Westport in 1894.

When mayor, the Slavens family lived on Quality Hill. The Slavens family lived at the southwestern corner of 10th & Jefferson Streets in Kansas City. They then lived at 3200 Main Street. Around 1895, they lived at 3016 Oak Street.
