Until January 1, 2007 Ullerslev Municipality was a municipality (Danish: kommune) in the former Funen County, on the east coast of the island of Funen, in central Denmark. The municipality covered an area of 54 km, and had a total population of 5,190 (2006). Its last mayor was Erik Christensen, a member of the Social Democrats.

Ullerslev Municipality bordered Munkebo Municipality to the north, Langeskov and Årslev Municipality to the west, Ørbæk Municipality to the south and Nyborg Municipality to the east.

The municipality ceased to exist as the result of Kommunalreformen 2007 (the Municipality Reform of 2007). It was merged with Nyborg and Ørbæk municipalities to form a new Nyborg municipality. The new municipality belongs to Region of Southern Denmark.

In the Middle Ages, when Denmark was divided into hundreds, the area of Ullerslev Municipality was under Vindinge Hundred. In 1662 counties were established, and Ullerslev came under Nyborg County. It merged with Tranekær County in 1793 to form Svendborg County. In the 1970 Danish Municipal Reform Svendborg County was merged with Odense County to form Funen County. After the 2007 municipal reform Funen County came under the Region of Southern Denmark.

From 1842, where parish municipalities were created, and until 1937 the area of Ullerslev Municipality consisted of just two parish municipalities. The Flødstrup-Ullerslev Parish Municipality was split in two in 1937, with Flødstrup and Ullerslev becoming independent parish municipalities. Ullerslev merged with Skellerup-Ellinge Parish Municipality in 1964 however. In 1970 the two parish municipalities of Ullerslev and Flødstrup merged to form Ullerslev Municipality.

In the Municipality Reform of 2007 Ullerslev Municipality was merged with Nyborg and Ørbæk Municipality to form a new Nyborg Municipality.

It was in 2005 suggested that Ullerslev should not only be merged with Nyborg and Ørbæk, but also with the municipalities of Munkebo, Langeskov and Kerteminde to create one large Eastern Funen municipality. The reason was that the new Kerteminde Municipality would have too small of a population to function properly. In the end, Nyborg and Kerteminde weren't merged and became two separate municipalities.
