The Minnesota Young DFL (simply referred to as MYDFL, also YDFL) is the official youth caucus of the Minnesota Democratic–Farmer–Labor Party (DFL). The group's membership is open to any Minnesotan Democrat under the age of 36. The Minnesota Young DFL is nationally affiliated with the Young Democrats of America. Its current president is Quentin Wathum-Ocama.

In 1944, the Minnesota Farmer–Labor Party and the Minnesota Democratic Party united to form the DFL.

The Minnesota Young DFL was formed in 1947 by University of Minnesota student William G. Kubicek, who became the YDFL's first chairman.

The young DFL was brought in a struggle between the left-wing and right-wing factions of the DFL. Under Kubicek, the YDFL would be dominated by the party's right. In contrast, the state leadership, led by Harold H. Barker, was dominated by the party's left. In December of 1947, the YDFL and Barker's DFL found themselves so divided, Barker considered taking legal action against the YDFL for failing to conform to the larger party's platforms and leadership. By late January of 1948, the YDFL had been rejected by the DFL leadership. The YDFL attempted to hold an independent convention separate from the DFL convention, which the DFL leadership considered illegal.

While still in this perilous position, it provided an early endorsement for then-Minneapolis Mayor (and unifying force in the party) Hubert H. Humphrey's U.S. Senate run. As Walter F. Mondale recalls (then a student at Macalester College):

Afterward, Mayor Humphrey received the endorsement and a month later at the state convention did the same. "He had the numbers and he won the crowd, and after that the party belonged to him."

By the end of 1949, Humphrey and his allies had successfully taken control of the DFL and reintegrated the YDFL without issue.

In 1951, the YDFL did a tour of the state, meeting with local college DFL clubs. At this time, Duane Emme was chairman.
