Kenichi Fukui, Japanese chemist and academic, Nobel Prize laureate (d. 1998)
Kenichi Fukui (福井 謙一 Fukui Ken'ichi, October 4, 1918 – January 9, 1998) was a Japanese chemist, known as the first Asian person to be awarded the Nobel Prize in Chemistry.

Fukui was co-recipient of the 1981 Nobel Prize in Chemistry with Roald Hoffmann, for their independent investigations into the mechanisms of chemical reactions. Fukui's prize-winning work focused on the role of frontier orbitals in chemical reactions: specifically that molecules share loosely bonded electrons which occupy the frontier orbitals, that is the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO).
