Kentucky's 4th congressional district is acongressional district in theU.S. state ofKentucky. Located in the northeastern portion of the state, it is a long district that follows theOhio River. However, the district is dominated by its far western portion, comprising the eastern suburbs ofLouisville andNorthern Kentucky, the Kentucky side of theCincinnati area. It is the richest congressional district in the state ofKentucky.^[4]

The majority of voters live in thesuburban Cincinnati counties ofBoone,Kenton, andCampbell, which includes such suburbs asFort Mitchell,Covington,Florence,Newport, andFort Thomas. The next-largest population center is the northeastern suburbs of Louisville. It stretches as far south as northern portions of the city ofBardstown.

The district is currently represented byRepublicanThomas Massie, who was elected in a special election in 2012 to succeedRepublicanGeoff Davis, who resigned on July 31, 2012, citing family concerns.

The 4th was one of the first areas of Kentucky to turnRepublican outside of traditionally Republican south-central Kentucky; it has been in GOP hands for all but six years since 1967. Its politics are dominated by Republicans in the wealthy Cincinnati suburbs, which have swelled with former Cincinnati residents since the early 1960s. Between them, Boone, Kenton and Campbell counties have as many people as the rest of the district combined. As a measure of how much the Cincinnati suburbs have dominated the district, when Massie took office, he became the first congressman from the district's eastern portion in 45 years. Nonetheless,Democrats still hold state and local offices in rural counties.

On July 1, 2025, the district had 592,869 registered voters, who were registered with the following parties.
