Smile.DK是来自瑞典的流行音乐组合，现在由Malin Kernby和Veronica Larsson组成。她们的歌曲"Butterfly"在跳舞机流行的年代里广受欢迎，这也是她们及她们的歌曲在全世界风靡的原因之一。

虽然她们的组合名称Smile.DK中含有DK两个字母（丹麦的简写），但Malin,Veronica及前成员Nina都不是丹麦人，她们全都来自瑞典。她们的专辑在丹麦发行，所以加上了.DK的后辍。
Veronica和Nina最初组建了名为Smile的乐队并且在1998年发行了她们的第一张专辑《Smile》。《Smile》受到了广泛的关注，特别是在日本。专辑中的一些歌曲被EMI收录，其中的Butterfly最终经Konami授权成为第一代跳舞机舞曲。从那以后，Butterfly成为跳舞机历史上最受欢迎的歌曲。
在第一张专辑之后，Nina离开了Smile开始单飞，Veronica取代了Nina加入到Smile。乐队名称也从Smile变成了Smile.DK.

她们第二张专辑中的"Kissy Kissy"也成为跳舞机游戏EZ2Dancer中的经典。

SMiLE.dk is a Swedish pop duo with the singers Veronica and Hanna from Sweden. Their mission is to entertain and create happiness through their catchy lyrics, upbeat sound & tender sensitive ballads, and of course the tracks are bound together by their beautiful voices!

They are a Swedish dance/pop group that has consisted of 4 members over time: Veronica Almqvist, Nina Boquist, Malin Kernby, and Hanna Stockzell. Despite what the group name suggests, the members are not Danish; they are all from Sweden. They were signed at EMI in Denmark, and when the first album "SMiLE" were released in Japan they found out that there existed a Japanese rock-group also named "Smile". To avoid misunderstandings the recordcompany added .dk after the group-name, hence the ".dk" tag.
