Fanning is an unincorporated community in western Crawford County, Missouri, United States. It lies along former U.S. Route 66, now Missouri Supplemental Route ZZ, five miles (8 km) west of Cuba. Fanning is also home to the world's largest rocking chair, located outside of the Fanning 66 Outpost.
Fanning is named for John Fanning (1821-1906), originally of Limerick, Ireland. John Fanning was the founding railway section foreman beginning in the mid-19th century when the St. Louis-San Francisco Railway (Frisco) was first built through the region. His home, which still stands in Fanning, was for many decades the railway station, church, post office, and social center of the community. Fanning descendants still live in Fanning and the surrounding area.
