Note: age at the end of the Lord of the Rings books, that is — in the year T.A. 3019.
51 years old!
Frodo Baggins was 51 by the end of The Lord of the Rings. He was 50 years old at the Council of Elrond, and 33 at the beginning of The Fellowship of the Ring. The One Ring sure keeps you looking young!
2,778 years old!
At the end of the trilogy, Arwen is 2,778, yet doesn't look a day over 1,000! Being half-Elven has its perks. Fun fact: she gives up her life at age 2,901, a year after Aragorn's death.
88 years old!
Aragorn was 88 at the end of the series, and ruled for 122 years as king until his death at 210 years of age.
129 years old!
Bilbo Baggins is 129 by the end of The Lord of the Rings. The Fellowship of the Ring opens on his "eleventy-first" birthday.
140 years old!
By the end of the trilogy, Gimli was 140. At age 262, Gimli traveled into the West to the Undying Lands with Legolas after Aragorn's death.
24 years old!
Éowyn was only 24 at the end of the LOTR series, further proving that she is more badass than us all. Her brother Éomer was 28.
29 years old!

36 years old!
At the end of the series, Faramir was 36. Meanwhile, his brother Boromir died at 41.
70 years old!
Théoden died in battle at age 70. Éomer succeeded him as king.
Around 589 years old!
Possessing the One Ring extended Gollum's life far beyond what it would have naturally been, and he was around 589 years old at the time of his death in Mount Doom.
