Tesseropora rosea, the rose barnacle, is a species of barnacle found in eastern and southern Australia, and South Africa.

The rose barnacle's hard exterior is grey to whitish with four shell plates. Larger specimens show a pinkish colour. Size is 20 millimetres across to 12 millimetres tall. Their habitat is exposed rocky shores, from high tide levels to a depth of 58 metres; the barnacles are able to tolerate strong wave activity. They feed on plankton and small particles.

Rose barnacles have a steep, conical shell with an outer wall made up of four plates. The base of shell is usually around 1.9 centimetres (0.75 in) in diameter but may exceed 2.5 centimetres (0.98 in); the barnacles typically grow 1.3 centimetres (0.51 in) tall. The central triangle-shaped portions of these plates are called parietes – which in this species have each a single row of large, square pores or tubes. The colour of the shell among younger barnacles is pale grey, but the shell pinkens as it ages.
