The League for Yiddish (in Yiddish: ייִדיש־ליגע) is a global, non-profit membership organization that promotes and encourages the active use of the Yiddish language in all areas of daily life. It is a charity with 501(c)(3) tax-exempt status, incorporated in the State of New York, U.S. The members of its board of directors and its staff live in the United States, Canada, and Israel. The League for Yiddish is one of the few secular Jewish organizations in the world that carries out nearly all its activities – from public events to staff meetings – in Yiddish.

The organization was founded as the Freeland Territorialist League of America for Jewish Colonization (in Yiddish: פֿרײַלאַנד־ליגע) in London in 1935 and incorporated in New York State in 1942.^[1] The Freeland League advocated for the creation of Yiddish-speaking Jewish territories in every country in which Jews were present.^[5]

With the cessation of its territorialist activity decades earlier, the Freeland League officially changed its name to the League for Yiddish on September 13, 1979, in order to continue its focus on promoting Yiddish as a living language.^[1][6]

The goals of the League for Yiddish are to:

• Encourage people to speak Yiddish in their everyday life;
• Enhance the prestige of Yiddish as a living language, both within and outside the Yiddish-speaking community; and
• Promote the modernization of Yiddish.

Organizational programs provide an array of resources and activities to ensure the relevance of the Yiddish language to contemporary life.

The organization's publications include the following.^[7]

• Afn Shvel (in Yiddish: אויפֿן שוועל – "On the Threshold") is the League's magazine and the only all-Yiddish general interest magazine currently in print. The magazine was originally founded in 1941 as the voice of the Freeland League; with the dissolution of that organization, the magazine likewise changed its content and presentation. Today, Afn Shvel is the world's oldest, continuously published print Yiddish magazine. Selected articles published in previous issues of Afn Shvel are available for digital download on the organization's website. Its editors have included the following.^[8]
