Lotta på Liseberg (Lotta at Liseberg), also called Allsång på Liseberg (Sing-along at Liseberg), is a Swedish sing-along show held at Stora scenen at the amusement park Liseberg in Gothenburg every Monday evening during the summers since 2004, hosted by Lotta Engberg and conducted by Curt-Eric Holmquist, the pianist.

It is produced by Eyeworks.

In December 2005 a winter sing-along show called Jul-Lotta på Liseberg (Christmas-Lotta at Liseberg) started ("Jul-Lotta"="Julotta + Lotta").

The intro-song is "Hej, mitt vinterland" and the outro-song "O Holy Night" (O helga natt in Swedish).

The show is broadcast on Sundays during the Christmas time and there are 4 programs.
