Susan Hareho Karike Huhume (c. 1956–11 April 2017) was a Papua New Guinean housewife, who, as a schoolgirl, designed the colours of her country's national flag.

[3] Karike did not believe the original colours of blue, yellow and green were traditional enough,[6] nor did she like the vertical stripes that the flag was split into.

[7] She used a diagonal line and the colours red, black and yellow, as well as keeping the motifs of the Southern Cross and the bird of paradise.

[5] The new design for the flag was drawn in a page torn from her exercise book.

[3] Despite designing the colours of the national flag, Karike's achievement went largely unrecognised during her lifetime.
