Nielsen Media Research (NMR) is a U.S. firm, headquartered in New York City, and operating primarily from Oldsmar, Florida, which measures media audiences, including television, radio and newspapers. NMR is best-known for the Nielsen Ratings, a measurement of television viewership.

Nielsen Media Research began as a division of ACNielsen, a marketing research firm. In 1996, Nielsen Media Research was split off into an independent company, and in 1999, was purchased by the Dutch conglomerate VNU. In 2001, VNU also purchased ACNielsen, thereby bringing both companies under the same corporate umbrella.

Nielsen Media Research is a sister company to Nielsen//NetRatings, which measures Internet and digital media audiences, and Nielsen BuzzMetrics, which measures Consumer-Generated Media.
