Julius Brammer (9 March 1877 – 18 April 1943) was an Austrian librettist and lyricist, renowned for his contributions to the operetta genre during the Vienna "Silver Operetta Period" from about 1900 to 1920. Born in Sehraditz, Moravia (now Sehradice, Czech Republic), Brammer was the son of Hermann and Julie. He initially trained as an actor, performing at the Staatstheater am Gärtnerplatz in Munich before moving to Vienna, where he became involved in operetta productions at the Theater an der Wien.

In 1908, Brammer shifted his focus to writing libretti, often collaborating with Alfred Grünwald. He worked with notable composers such as Emmerich Kálmán, Oscar Straus, Leo Ascher, Edmund Eysler, and Robert Stolz. Some of his well-known works include "Gräfin Mariza" (Countess Maritza) and "Die Bajadere" (The Yankee Princess).

One of Brammer's most enduring contributions to music is the song "Schöner Gigolo, armer Gigolo" (Just a Gigolo), with music by Leonello Casucci. This song has been recorded by numerous artists, including Bing Crosby and Louis Armstrong, and remains popular in various translations.

As a Jew, Brammer was forced to flee Austria after the Anschluss in 1938, relocating first to Paris and then to the unoccupied south of France during World War II. He died in Juan-les-Pins, Alpes-Maritimes, France, in 1943. His legacy endures through his contributions to the operetta and popular music.
