The Lamplighter Stakes is an American Thoroughbred horse race run annually during the last week of May at Monmouth Park Racetrack in Oceanport, New Jersey. Open to three-year-old horses, it is contested on turf over a distance of 1+1⁄16 miles (8.5 furlongs).

Inaugurated in 1946 as the Lamplighter Handicap, the race was named to honor Lamplighter, the 1893 American Co-Champion Older Male Horse owned by prominent horseman Pierre Lorillard IV who had been a co-owner of the Monmouth Park Association's racetrack.

Since its inception, the race has been contested at various distances on both dirt and turf:

• 1+1⁄16 miles on dirt : 1946–1970, 1972, 1974, 1984,1987
• 1+1⁄8 miles on turf : 1971
• 1+1⁄16 miles on turf : 1973, 1975–1983, 1985–1986, 1988–2004, 2007–present
• 1 mile on turf : 2005, 2006

On July 1, 1978 the legendary U.S. Racing Hall of Fame inductee, John Henry, made his turf stakes debut with a third-place finish in the second division of the Lamplighter.
