Barbra Streisand announced Thursday that she will embark on a national concert tour this fall, her first in over a decade.

Streisand will play 20 concerts in U.S. cities during October and November, her manager, Martin Erlichman, said in a statement. Her last U.S. tour was in 1994.

The 64-year-old singer-actress plans to give "designated proceeds" from the tour to support several causes, including the environment, education and women's health. The money will be distributed through the Streisand Foundation.

"The increasingly urgent need for private citizen support to combat dangerous climate change, along with education and health issues, was the prime reason I decided to tour again," Streisand said in a statement. "This will allow me to direct funds and awareness to causes that I care deeply about."

The tour follows the release of her latest album, "Guilty Pleasures," last September. In 2004, Streisand marked her return to the big screen, co-starring in the Ben Stiller comedy, "Meet the Fockers."

Dates and locations will be announced at a later date.
