DumbLand is a series of eight animated shorts written, directed and voiced by director David Lynch in 2002. The shorts were originally released on the Internet through Lynch's website, and were released as a DVD on March 28, 2006. The total running time of all eight shorts combined is approximately a half-hour.

The series details the daily routines of a dull-witted white trash man. The man lives in a house along with his frazzled wife and squeaky-voiced child, both of whom are nameless as is the man in the shows. Lynch's website, however, identifies the male character by the name Randy and the child by the name Sparky. The wife is not named.

The style of the series is intentionally crude both in terms of presentation and content, with limited animation.
