Morgnshtern (מאָרגןשטערן, Yiddish for 'Morning Star', sometimes also known by its Polish name Jutrznia) was a Jewish sports organisation in interbellum Poland, politically linked to the Bund.

In 1937 Morgnshtern had prepared a delegation to take part in the Workers Olympics in Antwerp, Belgium, but the Polish government refused to give travel visas to the athletes.

[citation needed] Morgnshtern espoused principles of socialist sporting, seeking to promote proletarian camaraderie and collective achievements, rather than individual competition.

[9] However, in order to increase recruitment the organisation eventually began opening up for more individually oriented competitive sports such as football, table tennis and boxing.

Still though, compared to the Shtern federation of the Poale Zion Left or bourgeois Jewish sports organisations, Morgnshtern put very little emphasis on football.

The two organisations clashes at the 1929 Prague congress of the Socialist Workers' Sports International, as Morgnshtern demanded to be recognized as a separate section and not as an affiliate of the Polish ZRSS.

[9] The full name of the organization was Arbeter Gezelshaft far fizisher Dertsiung "Morgnshtern" in Poyln in Yiddish, and Robotnicze Stowarzyszenie Wychowania Fizycznego "Jutrznia" w Polsce in Polish.

[3][11] The emblem of Morgnshtern featured a javelin thrower, illustrated in the style of a classic Greek statue, in front of belching smokestacks.
