UFO Baby (だぁ!だぁ!だぁ!, Dā! Dā! Dā!) is a Japanese shōjo comedy manga by Mika Kawamura, serialized by Kodansha in Nakayoshi from February 1998 to March 2002 and collected in nine volumes. The series was adapted as a 78-episode anime television series, produced by NHK and animated by J.C.Staff, which was broadcast between March 2000 and February 2002 on NHK's BS2 broadcast satellite network. While the anime concluded before the manga, Kawamura later wrote a sequel titled Shin Daa! Daa! Daa! (新☆だぁ!だぁ!だぁ!).
