"I Am Woman" is a song written by Australian-American artist Helen Reddy and singer-songwriter Ray Burton and performed by Reddy. The first recording of the song appeared on Reddy's debut album I Don't Know How to Love Him, released in May 1971, and was heard during the closing credits for the 1972 film Stand Up and Be Counted. A new recording of the song was released as a single in May 1972 and became a number one hit later that year, eventually selling over one million copies. The song came near the apex of the counterculture era and, by celebrating female empowerment, became an enduring anthem for the women’s liberation movement.

After securing a recording contract in 1971 with Capitol Records that yielded the hit "I Don't Know How to Love Him", Reddy – then living in Los Angeles – was asked for an album. She gave the label a set of 10 jazz-tinged pop songs. Nestled among the Leon Russell, Graham Nash and Van Morrison songs were two Reddy and Burton originals. "I Am Woman" was one of them. The composition was the result of Reddy’s search for a song that would express her growing passion for female empowerment. In a 2003 interview in Australia’s Sunday Magazine (published with the Sunday Herald Sun and Sunday Telegraph), she explained:

I couldn't find any songs that said what I thought being woman was about. I thought about all these strong women in my family who had gotten through the Depression and world wars and drunken, abusive husbands. But there was nothing in music that reflected that.

The only songs were 'I Feel Pretty' or that dreadful song 'Born A Woman'. (The 1966 hit by Sandy Posey had observed that if you're born a woman "you're born to be stepped on, lied to, cheated on and treated like dirt. I'm glad it happened that way".) These are not exactly empowering lyrics. I certainly never thought of myself as a songwriter, but it came down to having to do it.
