This is the first comprehensive review on inherent anisotropic features of transition metal diboride (MB
2
) and their implementation for tailoring the microstructure and properties of MB
2
-based Ultra-high temperature Ceramics (UHTCs). The emphasis is on the processing approaches, microstructures, and properties of self-reinforced and/or textured MB
2
-based composites with elongated MB
2
grains. The crystal structure characteristics and grain growth behaviour of MB
2
are also critically reviewed. Benefiting from the tailored microstructure, the MB
2
-based ceramics exhibit some improved properties. Considering the success of Si
3
N
4
ceramics in the field of structural ceramics, it is expected that the potential MB
2
-based ceramic composites with abundant elongated MB
2
grains, textured structures, and controlled grain boundaries would possess improved fracture toughness, thermal shock resistance, and reliable high-temperature properties, which are desired for their practical applications. Accordingly, microstructure designing and tailoring provide an important perspective for the future development of UHTCs.
