Well, to make a long story short, Barbra Streisand is Jewish!
Since Barbra Streisand's mother is Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes her Jewish. Her father is Jewish too.
Barbra Streisand (whose full birth name is Barbara Joan Streisand) was born on April 24, 1942 in Williamsburg, Brooklyn, New York, U.S..
She has won two Academy Awards, eight Grammy Awards, five Emmy Awards, a Special Tony Award, and is one of the few entertainers who have won an Oscar, Emmy, Grammy, and Tony Award. She is one of the most commercially and critically successful entertainers in modern entertainment history, with more than 71.5 million albums shipped in the United States and 145 million records sold worldwide.
Some of the films she starred in are: Funny Girl (1968), Hello, Dolly! (1969), The Owl and the Pussycat (1970), The Way We Were (1973), A Star Is Born (1976), Yentl (1983) and The Prince of Tides (1991).
