"I Should Be So Lucky" is a song written and produced by Stock Aitken Waterman.

Performed by Kylie Minogue it became her debut worldwide hit, the song topping the charts in countries such as the United Kingdom, Australia and Germany and peaked in the top ten in many countries including New Zealand, Japan and the Dance charts in the U.S.

After the success of her debut single "Locomotion" in Australia, Minogue traveled to London to work with Stock Aitken Waterman, a successful British writing and production team. They knew little of Minogue and had forgotten that she was arriving; as a result, they wrote "I Should Be So Lucky" in forty minutes while she waited outside the recording studio. Mike Stock wrote the lyrics for the song in response to what he had learned about Minogue prior to her arrival. He believed that although she was a successful soap star in Australia and very talented, there must be something wrong with her and figured that she must be unlucky in love. Minogue recorded the song in less than an hour, which Stock attributes to her good ear for music and her quick memorisation skills. After Minogue finished the recording session she returned home to Australia to continue work on the soap opera, Neighbours. Stock later said: "We had to get the song together in about 40 minutes and she left not having had a happy experience. We didn’t know we had a hit on our hands and so when it went to No 1 for five weeks, someone said: "What’s the follow-up?” We didn't have one. So I went out to Australia at the start of 1988 and met her in a bar with Jason and her manager. I basically crawled 100 yards on my knees and apologised profusely."

"I Should Be So Lucky" was released in the UK on 29 December 1987, and in Australia on 1 February 1988. It was a commercial success, reaching atop the Australian Kent Music Report chart for six consecutives weeks, and became her second number-one single, following Locomotion. The single was certified platinum by the Australian Recording Industry Association (ARIA) and ranked at number five on the Year-end chart for 1988. In New Zealand, the song entered at No. 15 on New Zealand Top 40 and peaked at No. 3 on 27 March 1988, spending twelve weeks on the chart. In United Kingdom, "I Should Be So Lucky" was released on 29 December 1987.
