How old is the oldest reindeer?

While there isn't a definitive record of the oldest reindeer ever, the average lifespan of a wild reindeer is around 10-15 years.

However, in captivity, they can live up to 20 years or more with proper care.

So, while we don't know the exact age of the oldest reindeer ever, it's likely that some have lived longer than the average wild lifespan.
