Evil beings worship evil powers – the orc pantheon is a group of such deities, led by the driven and aggressive Gruumsh.

Greater Deity:
Gruumsh, chaotic evil god of conquest

Lesser Deities:
Bahgtru, chaotic evil god of physical prowess
Ilneval, neutral evil god of war
Luthic, neutral evil goddess of the earth
Shargaas, chaotic evil god of the night
Yurtrus, neutral evil god of death

Orcs only very rarely spend time worshiping the members of other pantheons.
