We consider noncanonical embeddings of the MSSM in high-dimensional orbifold grand unified theories (GUTs) based on the gauge symmetry SU(N), N=5, 6, 7, 8. The hypercharge normalization factor k{sub Y} can either have unique noncanonical values, such as 23/21 in a six-dimensional SU(7) model, or may lie in a (continuous) interval. Gauge coupling unification and gauge-Yukawa unification can be realized in these models by introducing new particles with masses in the TeV range which may be found at the LHC. In one such example there exist color singlet fractionally charged states.
