Nowy Tomyśl [ˈnɔvɨ ˈtɔmɨɕl] is a town in western Poland, in Greater Poland Voivodeship. It is the capital of Nowy Tomyśl County. The population is 15,627 (2004).

The town has a long tradition of wickerwork. In the main town square stands a wicker basket woven in 2006, measuring 17 metres (56 ft) long, 9 m wide and 7.7 m high, entered in the Guinness Book of Records as the world's largest basket. The town also has a Museum of Basketry and Hop Growing, which is one of the branches of the National Museum of Agriculture in Szreniawa. Next to the museum is a small zoo.

Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the town was occupied by Germany until 1945. In December 1939, the German gendarmerie carried out the first expulsions of Poles, including families of intelligentsia, activists and owners of workshops, bakeries and restaurants, which were then handed over to German colonists as part of the Lebensraum policy. Expelled Poles were deported to a transit camp in Młyniewo, and then to the Radom District in the more-eastern part of German-occupied Poland. In January 1945, a German-perpetrated death march of prisoners of various nationalities from the dissolved camp in Żabikowo to the Sachsenhausen concentration camp passed through the town.

Since 2012, Nowy Tomyśl has been the site of one of the tallest wind turbines in the world.
