Delina Filkins (née Ecker;[1] 4 May 1815 – 4 December 1928) was an American supercentenarian, and the first person verifiably to reach the age of 113.

[2] In 1834, at the age of 18, Delina married local farmer John D. Filkins, going on to have at least six children: Joseph (1836–1891), Cornelia (1837–1900), William (1839–1909), Alonzo (1841–1929), Barney (1848–1928), and Frank (1854–1932).

[4] According to Robert Douglas Young, and as reported in newspapers during her later years, Filkins was known for her "hard work", "self-reliant philosophy", "tough personality" and "self-sufficiency", well into old age.

[2] It was noted, for example, that at the time of her birth James Madison was President of the United States, and she could remember when the Erie Canal was opened.

[2] Delina Filkins died at the home of her grandson in Richfield Springs, New York on 4 December 1928, and the death was widely reported.

[6][7][8] In 2020, Robert Douglas Young conducted a close examination of Filkins' life to confirm the validity of the claim that she had been the first person to reach 113.
