No. In the episode "The Journal" They reveal his parents (Miles and Stella) are explorers. His mom is a Botanist and they went to South America because they heard of an unknown disease that was killing plants, animals, and humans. Sometime after Arnold is born (He was born during their trip), they go back to America. But they are called back to South America. So they give Arnold to Miles's parents and they take off.
Craig Bartlett created a follow up two hour movie set to air on Nickelodeon in November 2017 [exact date yet unknown] titled Hey Arnold Jungle Movie that will tie up the series and answer questions involving Arnold's missing parents.
