Neckarsulm (German pronunciation: [nɛkaʁˈzʊlm]) is a city in northern Baden-Württemberg, Germany, near Heilbronn, and part of the district of Heilbronn. As of 2016, Neckarsulm had 26,800 inhabitants. The name Neckarsulm derives from the city's location where the Neckar and Sulm rivers meet.

Neckarsulm is known for its renewable energy projects and wine. The Weingärtnergenossenschaft Neckarsulm-Gundelsheim (winegrower's cooperative of Neckarsulm and Gundelsheim) is the oldest winegrower's collective in Germany. The wine Trollinger and Lemberger are the principal varieties of grape grown in this region. The Schwarz Gruppe (Schwarz Group) who leads both companies Lidl and Kaufland has its headquarters in Neckarsulm.

Neckarsulm was first mentioned in a document in 771 and was granted city status around 1300. The city celebrated its 1250th birthday in 2021.

Neckarsulm is located on the eastern side of the Neckar River Valley. The town is approximately 30 kilometres (19 mi) from the Löwenstein Mountains and is part of the Swabian-Franconian Forest. The closest nearby city is Heilbronn, the sixth largest city in the federal state Baden-Württemberg.

The urban area of Neckarsulm consists of the city itself and the districts of Amorbach, Dahenfeld, and Obereisesheim.

Archaeological finds such as vessel shards indicate human activity in the greater Neckarsulm region as early as the middle of the 6th millennium B.C. (Neolithic period). In 2001, archaeologists found a Late Bronze Age burial ground in Trendpark-Süd (roughly on the modern day site of the German IT company "Bechtle"), which was dated to around 1100 BC on the basis of metal and ceramic finds. Graves found south of the old city wall indicate a Frankish settlement dating to the 7th century AD.

The town, formerly called "Sulmana" or "Sulmgau", is dated to the year 771 in a deed of donation to Lorsch Abbey. Sulmana is mentioned in the Lorsch Codex. The area became known as Neckarsulm in the 16th century.
