It's My Sin is the first studio album by the New Zealand singer-songwriter Jan Hellriegel, released on 7 September 1992 by East West Records.

[1][2][5] After the disbandment of her former band Cassandra's Ears, Hellriegel was signed to East West's parent company Warner Music International as a solo artist in 1989.

[1][2] Although she did not intend to embark on a solo career, she took up the label's offer as she was willing to move on from working at her father's business and had numerous unpublished songs that she wished to do more with.

These include "Westy Gals", an "interpretation of her [hometown] West Auckland" and its "masses of sprawling boredom", and "Richmond Rd Revisited", which tells of the "depressing time" she experienced while living in Grey Lynn.

[1][2] Reviews by The New Zealand Herald and Sunday Scene both awarded it a perfect five stars, the Sound Advice newspaper gave it 3.5 stars, and numerous other reviewers were well-pleased with the album, complimenting Hellriegel's "rich, robust vocals," "neat guitar melodies," and the overall "great collection of music."

The commercial and critical success was a surprise to Hellriegel, who was not expecting many people beyond her friends to purchase the album or its singles.
