Acacia cyperophylla, commonly known as creekline miniritchie or red mulga, is a tree in the family Fabaceae.

[3] It is commonly found growing in areas of slightly higher soil moisture such as in drainage lines and on the banks of rivers and creeks.

These are rigid, round in cross-section with a diameter of about two millimetres, between ten and fifteen centimetres long, and curved.

Creekline miniritchie is most readily identified by its distinctive "minni ritchi" bark, which constantly peels off in small curling flakes, making the tree look like it has a coat of curly hair.

omearana has been classified "Priority 1" under the Western Australian Wildlife Conservation Act, and is under consideration for declaration as "rare flora".
