"It's No Secret" is a song by Australian singer-songwriter Kylie Minogue taken from her debut studio album Kylie (1988). The song was written and produced by Stock, Aitken and Waterman, who were also the producers of Minogue's first four studio albums. The song was intended to be released as the fifth single from Kylie, but due to the success and longevity of Kylie's massive selling duet with Jason Donovan, "Especially for You", over Christmas 1988 and the following new year, it was only released in a handful of countries. In the United States, "It's No Secret" was released as Kylie's third single where it reached the top 40 of the Billboard Hot 100.

In the UK "It's No Secret" featured as the B side to the single "Wouldn't Change A Thing".
