Myosotis brockiei is a species of flowering plant in the family Boraginaceae, endemic to southern South Island of New Zealand.

Plants of this species of forget-me-not are perennial rosettes which form loose tufts or clumps, with ebracteate, erect inflorescences, and white corollas with exserted stamens.

The upper surface of the leaf is densely covered in mostly flexuous, some curved, patent to erect, antrorse (forward-facing) hairs that are oriented oblique to the mid vein.

Each rosette has 1–6 erect, usually once-branched (sometimes unbranched), ebracteate inflorescences that are up to 385 mm long and are usually bifurcating in an open, forked 'V' shape near the tips.

[3] The holotype specimen of Myosotis brockiei was collected from Gorge of the Cobb River, Western Nelson, South Island, New Zealand by W.B.

[10][3] The specific epithet, brockiei, honors the collector of the type specimen, Walter Boa Brockie (1897–1972) who was a New Zealand botanist and horticulturist.

[3] The species is listed as At Risk - Naturally Uncommon on the most recent assessment (2017-2018) under the New Zealand Threatened Classification system for plants, with the qualifier "RR" (Range Restricted).
