Boechera holboellii, or Holbøll's rockcress, is a species of plant in the family Brassicaceae.

Its cytology has been much studied by the Danish botanist Tyge W. Böcher.

[3] The rust fungus Puccinia monoica infects the plant leading to pseudoflowers, which mimic those of yellow, early spring wildflowers (e.g. buttercups), not only in visible light but also in ultraviolet.

[4] The specific epithet commemorates Carl Peter Holbøll - a Danish civil servant and early explorer of the fauna of Greenland.

[3] It is not clear whether polyploids of B. holboellii (as narrowly defined) exist.
