Angela Raubal Hamitsch, born Angela Hitler (July 28, 1883 - October 30, 1949), was the elder half-sister of Adolf Hitler.

She was born to Alois Hitler and his second wife, Franziska Matzelberger in Braunau, Austria. Her mother died the next year and she and her brother Alois Hitler, Jr., were raised by their father and his third wife, Klara Hitler. Adolf Hitler was born in 1889; she and her half-brother grew very close, and she is the only one of his siblings mentioned in Mein Kampf.

Her father died in 1903 and her stepmother passed away in 1907 leaving a small inheritance. By this time she had married Leo Raubal, a junior tax inspector, and, in 1906, given birth to a son also named Leo. In 1908, she gave birth to Geli and in 1910 to a second daughter Elfriede.

Leo Raubal died on August 10, 1910. According to an OSS profile of the Hitler family, Angela then moved to Vienna and, after World War I became manager of Mensa Academia Judaica, a boarding house for Jewish students and, at one point, defended her charges against anti-Semitic rioters.

Angela had not been in contact with Adolf for a decade when he re-established contacted with her in 1919. In 1928 she and Geli moved to Obersalzberg where she became his housekeeper. She was later put in charge of the household at Hitler's retreat Berchtesgaden.

Adolf Hitler is thought to have begun a relationship with Geli who committed suicide 1931.

Angela is reported to have strongly disapproved of Hitler's subsequent relationship with Eva Braun (though some report that she tried to warn Eva Braun of the dangers of getting involved with Hitler). She left Berchtesgaden and moved to Dresden. Adolf Hitler broke off relations with her and did not attend her wedding to Professor Hamitsch.
