Greek gods are known to be immortal, but their myths often have them fighting against other gods and being defeated. Did Greek gods ever die? Could they even be killed in the first place?
The Olympian gods don’t ever die and aren’t permanently defeated in any myth. Greek gods were immortal, so they couldn’t be killed. However, they could be cast away or permanently incapacitated. Greek mythology doesn’t have a story for the death of its gods like Norse and other mythologies do.
Technically, Greek gods couldn’t die, but there are some myths where a God goes through a symbolic death, to the point that they don’t appear ever again in other myths. Here’s what happened to Greek gods when they were defeated.

Can Greek Gods Be Killed?
Greek Gods are immortal, which means they can’t be killed. They could, however, hurt each other and be maimed. There are some instances of gods being permanently defeated and disappearing afterward, like Uranus and the Titans, but they aren’t truly killed.
There are instances of gods being hurt by other gods or being permanently maimed. For example, Haephestus remained crippled after Zeus threw him off Mount Olympus. But there are no records of Greek gods being killed in a normal sense.
Instead, in the few cases when Greek gods are defeated permanently, they’re either exiled or maimed to the point that they can’t recover.
The first major example of a God being permanently defeated is Uranus. He was the primordial god of the sky, and together with Gaia, gave birth to the first generation of gods: the Titans.
Cronos, one of the Titans, eventually rebelled and castrated Uranus with a sickle. After this event, Cronos becomes the leader of the gods, and Uranus disappears. Although it isn’t stated that Uranus dies, he doesn’t appear ever again, as if he had faded away.
The Titans would eventually suffer a similar fate. Here we come to the second major story of gods “dying.”
Cronos was prophesied that one of his sons would overthrow him, just as he overthrew his father, Uranus. In an attempt to avoid this, Cronos decided to eat all his offspring as soon as they were given birth by his partner, Rhea.
Rhea managed to save one of her sons by hiding him away and giving Cronos a stone wrapped in cloth instead. This son was Zeus, who was raised by nymphs on the far-away island of Crete.
When he came of age, Zeus plotted a trick to make Cronos regurgitate his siblings. With their help, they started a war on the Titans.
After a long conflict, Zeus and the Olympians won and cast the Titans into a pit at the bottom of Tartarus. It is made clear that the Titans may never escape their prison since it is surrounded by walls and guarded by Poseidon.
The Titans never leave their prison, so they come as close to dying as Greek gods can. It could be said that the Olympian gods would have remained “dead” inside Crono’s stomach if Zeus hadn’t saved them.
There are also some examples of gods going through death and rebirth, as in the case of Dionysus.
Dionysus, god of wine and pleasure, traveled through the Underworld once to rescue his mortal mother, Semele. Some myths say that at some point of this journey, the Titans sliced him up, threw the bits into a cauldron, and ate him, leaving only his heart.
Depending on the myth, Demeter or Rhea then used Dyonisuis’ heart to restore him to health.

Were Greek Gods Immortal?
Greeks believed that immortality was the main feature that distinguished gods from mortals. Immortality meant to be immune to death as well as having eternal youth.
However, in practice, this distinction wasn’t always clear-cut.
Some creatures were immortal but not god-like, like nymphs and satyrs. These supernatural creatures were ranked below gods but often surrounded them and attended their feasts.
Many myths feature mortals that end up being immortalized in some way. For example, Callistus was transformed into a bear and hunted down by Artemis, but as she died, she was placed among the stars as the constellation Ursa Major. Some heroes, like Heracles, were raised to godhood after they died.

Can Demi-Gods Be Killed?
Demi-gods in Greek mythology could be killed, but they often remained immortal in some way. Many characters in Greek mythology had divine blood but were still mortal.
Usually, one of their parents was a god and the other a human. For example, Achilles was the son of King Peleus and goddess Thetis.
There are some exceptions. Notably, Dyonisius had a mortal mother, yet he was a fully-fledged god.
Demi-gods lived moral lives and could certainly be killed, although with much effort. Because of their divine blood, they often had extraordinary power.
Achilles was an unparalleled warrior and even managed to fight and win against a river deity. He was eventually killed by the bow of Paris, who was assisted by the god Apollo.
Heracles performed many amazing feats, like restraining the three-headed hound Cerberus. He died because of a trick that had him touch the poison of his own arrows.
Demi-gods often won a special condition after they died. Heracles was raised to Olympus to live with the gods, and Achilles had a privileged place among the shades of the Underworld.

Could Zeus Die? Did He?
Zeus couldn’t die. He doesn’t die in any myth. Like the rest of the Greek gods, he was immortal. Zeus was also the most powerful god, so he couldn’t be defeated.
In Greek mythology, gods are timeless. That means there isn’t an end to the rule of Zeus and his brothers, Poseidon and Hades. The Olympians are implied to exist and rule forever, unlike their predecessors.
However, Zeus came close to “dying” in the sense his predecessors died —that is, to be incapacitated and cast away.
After defeating the Titans, an Oracle told Zeus that his son with goddess Metis would overthrow him.
It would seem that Zeus was destined to suffer the same fate as his father and grandfather. However, Zeus prevented this by swallowing Metis whole. Later, Athena was birthed directly out of Zeus’ head, already clad in armor.
Metis is the goddess of prudence. It can be interpreted that he prevented ever being overthrown by integrating prudence into himself.
Could Poseidon Die? Did He?
Poseidon, like the other Greek gods, was immortal. Therefore, he doesn’t die in any myth. Poseidon, the ruler of the sea, was one of the most powerful gods, second only to Zeus.
After defeating the Titans, the three brothers distributed the ruling of the cosmos between themselves. Zeus got to rule over the land and heavens, Poseidon over the sea, and Hades over the Underworld.
Out of this story, it’s established that Poseidon has tremendous power and couldn’t be defeated in any plausible way.
Conclusion
Greek gods were immortal and couldn’t be killed. There are cases of gods being permanently exiled or incapacitated, which may be a symbolic death.
