Dallin (also Estrin, née Ginzberg) Liliya (Lilia) (born 1898, Libava/Liepāja – died c. 1981) — socialist activist and journalist.

Liliya Estrin studied law in Moscow in 1914 and became a member of the Menshevik party. In 1928 she emigrated to Berlin, where she married Samuel Estrin, a Leninist yet left-leaning dissident. After the Nazis rose to power in 1933, the couple relocated to Paris.

In Paris, she was employed at the International Institute of Social History as secretary to Boris Nikolaevsky. Together with Trotsky’s son, Lev Sedov, she co-edited the Trotskyist journal Bulletin of the Opposition and was involved in other party activities.

On 6 November 1936, NKVD operatives raided the institute and stole Trotsky’s documents. In March 1938, after Lev Sedov died of an unknown illness, suspicion fell upon Liliya and Mark Zborowski, who were accused of NKVD ties. Liliya managed to convince Trotsky of her innocence.

Following her emigration to the United States, she married David Dallin, a Menshevik and Russian historian who himself was suspected of NKVD connections. However, by 1944 evidence had emerged proving that Liliya Estrin was not an NKVD agent.
