Monster Bug Wars is a nature documentary program, created and distributed by Beyond Television Productions, and televised on the Science Channel in the United States, and SBS in Australia. The monster movie format features two kinds of insects, arachnids, myriapods, and other invertebrates in gladiator style combat in a simulated natural environment. In intermittent breaks, entomologists educate the viewer about the strengths and weaknesses of the dueling arthropods.

The opening narration is "In nature's fight pit, a host of ruthless bugs as bizarre as they are lethal slug it out in real-life battles to the death. Witness epic encounters between swarms of marauding assassins, and vicious one-on-one clashes where only one bug survives. The world of monster bugs is a jungle, where there's just one law: eat or be eaten."
