State Road 419 (SR 419) is a state highway in Seminole County, in Central Florida, United States.

SR 203 was defined without a number by 1931 state law, chapter 14921, approved May 29, 1931:

That certain road beginning at a point on State Road 3, approximately three miles south of the City of Sanford, where the present paved road to Oviedo intersects said SR 3; thence along said paved road to the intersection of Broadway and Bay Streets in the Town of Oviedo, Florida; and thence running in a southeasterly direction along the paved road, as now located, and known as the Chuluota-Oviedo Road, to Chuluota, Florida; thence continuing south along the Section line between Sections 28, 29 and 32 and 33, Township 21, Range 32, in the County of Seminole to its intersection with the Orange County line; and thence continuing on the present paved road to the intersection of said road with State Road 22.

In the 1945 renumbering, SR 203 became State Road 419.

The entire route is in Seminole County.
