Lucifer's Hammer is a science fiction post-apocalypse-survival novel by American writers Larry Niven and Jerry Pournelle that was first published in 1977.^[2] It was nominated for the Hugo Award for Best Novel in 1978.^[3] Two issues of a planned six-part comic book adaptation were published by Innovation Comics in 1993.^[4]

When wealthy amateur astronomer Tim Hamner co-discovers a new comet, named Hamner-Brown for its discoverers, documentary producer Harvey Randall persuades Hamner to have his soap company sponsor a television documentary series on the comet. Political lobbying by California Senator Arthur Jellison eventually gets a joint Apollo-Soyuz (docking with Skylab B) mission approved to study the comet, dubbed "The Hammer" by the media, which is expected to pass close to the Earth.

The scientific community assures the public that a collision with Earth is extremely unlikely, but the comet's nucleus breaks apart and the pieces strike parts of Europe, Africa, the Gulf of Mexico, and the Pacific and Atlantic Oceans. These result in volcanic eruptions, earthquakes, and tsunamis, destroying major coastal cities around the world, killing billions and initiating a new ice age because of the massive quantities of water and debris flung into the atmosphere.

Immediately after the strike, China, anticipating that the Soviet Union will become too cold for its people and must therefore invade its neighbor, launches a preemptive nuclear attack on its neighbor. The Soviets retaliate with their own nuclear missiles, reassuring the US that it is not the target.

Jellison has taken discreet precautions and moved his people and supplies to his ranch. He takes charge and organizes the easily protected valley in the Sierra foothills where his ranch is located, dubbed the "Stronghold". Randall and Hamner separately reach the valley and are allowed in (unlike almost all other refugees). Jet Propulsion Laboratory scientist and resident genius Dan Forrester receives a warm welcome when he reveals that he has hidden a cache of invaluable "how-to" books.

Other groups organize as well. The remnants of a United States Army unit, commanded by Sergeant Hooker, resorts to cannibalism to survive. They are joined by a criminal gang led by Alim Nassor. Together they search in vain for a place that is not too heavily defended, but capable of supporting them all. Reverend Henry Armitage, driven mad by the catastrophe, shows up and absolves the "New Brotherhood Army" of their crimes and cannibalism, stating that they have a mission from God to return humanity to a simpler, non-technological way of life. Their expansion is blocked by the Stronghold, which is also their only serious rival in numbers and strength. They attack, but Jellison's outnumbered forces defeat them with the help of mustard gas and other weapons produced by Forrester.

An operational nuclear power plant nearby is also a target of the New Brotherhood. The defenders barely survive the first assault and plead for help. Jellison's people are reluctant to send it, as the greatly weakened New Brotherhood no longer poses a threat to the Stronghold, but astronaut Rick Delanty gives them a stark choice: remain safe, though their descendants will be peasants, or attack and wipe out the New Brotherhood, and use the electric power to rebuild civilization. Just then, Jellison dies, but not before the ailing old man casts the deciding vote for the latter. They succeed, and later, it is shown that they are well on the way back to restoring civilization.

Niven and Pournelle originally pitched the story to publishers as an alien invasion story in which the aliens drop a comet onto Earth after humanity fights them. Jim Baen told them to write only the comet story. The original story idea was later written as their novel Footfall.

At least one reference to prior work by the authors is present in the text, through "Crazy Eddie's Insurance", a direct reference to The Mote in God's Eye (published in 1974).

Judith T. Yamamoto, in her review for the Library Journal, said that the novel was full of "good, solid science, a gigantic but well developed and coordinated cast of characters, and about a megaton of suspenseful excitement". Her one negative comment was that the pro-technology pitch might turn off some readers but "all in all it's a good book, if not a great one".^[5] Lucifer's Hammer received a nomination for the Hugo Award for Best Novel in 1978.^[3]

C. Ben Ostrander reviewed Lucifer's Hammer in The Space Gamer No. 13.^[6] Ostrander commented that "I recommend this book.... Don't miss it for a long, interesting story".^[6]
