Lina Beckmann was born in Hagen on April 21 1981. From 2001 until 2004, she studied acting at the Schauspielschule Bochum, which is part of the Folkwang Universität der Künste. Already as a student, she appeared in stage productions at the Schauspielhaus Bochum (2003/2004), the Prinzregenttheater (2004) and the Wuppertaler Bühnen (2004). In 2005, she began to work at the Schauspielhaus Zürich, and that same year she won the federal award for emerging acting talents. Two years later, Beckmann joined the ensemble of the Schauspiel Köln. In 2001, she was awarded the renowned Alfred-Kerr-Darstellerpreis for her performances in the Jelinek trilogy "Das Werk", "Im Bus", "Ein Sturz" and her portrayal of Warja in "Der Kirschgarten". The same year, the magazine "Theater heute" named her actress of the year. In 2013, she became a company player at the Deutsche Schauspielhaus in Hamburg. There, she received the 2015 Rolf Mares Preis for her performance in "Ab jetzt". Other memorable productions starring Beckmann include "John Gabriel Borkmann" and "Onkel Wanja".

In addition to her stage career, Beckamnn started to act for film and television in 2008. She had supporting roles in Lola Randl's "Die Besucherin" ("Days In Between", 2008), Ludi Boeken‘s Historiendrama "Unter Bauern" ("Among Peasants", DE/FR 2009), Jan Schomburg's "Über uns das All" ("Above Us Only Sky", 2011), Gregor Schnitzler's "Resturlaub" (2011) and Stephan Wagner's "Der Fall Jakob von Metzler" (2012, TV).

Her first leading role was as the wife of a crooked politician (Charly Hübner) in Arne Feldhusen's acclaimed TV satire "Vorsicht vor Leuten" (2015). Again playing opposite Hübner, she next starred in Adolf Winkelmanns Ruhrpott-Milieustudie "Junges Licht" ("Young Light", 2016). Lola Randl cast Beckmann and Hübner – also a couple in real life – as the leads of her comedy "Fühlen Sie sich manchmal ausgebrannt und leer?" ("Do You Sometimes Feel Burned Out and Empty?", DE/NL 2017), which was released in March 2018. Shortly afterwards, Beckmann guest-starred in the "Tatort" episode "Unter Kriegern" (2018, TV). While her film and TV career thrives, Beckmann is also still a company player at the Deutsche Schauspielhaus.      

In the fall of 2018, Beckmann received the German Acting Award in the category 'Actress in a Comedic Role' for her performance in "Fühlen Sie sich manchmal ausgebrannt und leer?". In early 2019 she won the German Film Critics Award for this part.  

Although her work in the ensemble of the Deutsches Schauspielhaus Hamburg remained Beckmann's main activity, she was subsequently seen in several television productions: Hermine Huntgeburth cast her in "Tödliches Comeback" as a policewoman and the main character's superior; in Sherry Hormann's two-part family epic "Altes Land" (2020), she had a leading role as a farmer. The "Polizeiruf 110" episode "Sabine" (2021) featured her alongside her husband Charly Hübner - as the half-sister of his detective Bukow.
