Alexandra C. Pelosi (born October 5, 1970) is an American journalist, documentary filmmaker, and writer based in New York City. She is the daughter of House Democratic leader Nancy Pelosi and Paul Pelosi.

In 2000, Pelosi worked as a network television producer for NBC covering George W. Bush's presidential campaign. She brought along a handheld camcorder documenting 18 months of her experience on the campaign trail; the footage was used to create Journeys with George, a documentary that earned her six Emmy nominations.

After spending a decade at NBC News, she left network news to work exclusively for HBO. During the 2004 Democratic primaries, she returned to the campaign trail, this time following the Democratic candidates. Her HBO documentary, Diary of a Political Tourist, was accompanied by her book Sneaking into the Flying Circus: How the Media Turn Our Presidential Campaigns into Freak Shows, about the process of selecting candidates for President of the United States. She stated that her conversations with Candy Crowley of CNN, Howard Dean, and Wesley Clark inspired her to write a book.

In 2006, she created the documentary about evangelical Christians called Friends of God: A Road Trip with Alexandra Pelosi which featured former pastor Ted Haggard. After it aired on HBO in 2007, she made a follow-up film, The Trials of Ted Haggard, chronicling the exile of Ted Haggard from New Life Church after his sex and drug scandal.

In 2008, Pelosi went back on the campaign trail to document the birth of the Tea Party movement at Republican campaign events for her film, Right America: Feeling Wronged - Some Voices from the Campaign Trail, which premiered on HBO on President's Day 2009.

CNN reported in July 2010 that Pelosi was no longer making political documentaries. Her 2010 HBO film, Homeless: The Motel Kids of Orange County follows the children of the working poor in Orange County, California.

In 2011, HBO debuted Pelosi's next film Citizen U.S.A.: A 50 State Road Trip. Pelosi traveled to all 50 states to attend naturalization ceremonies and interviewed immigrants as they became legalized American citizens. In 2013, she was at the Sundance Film Festival with her latest film, Fall To Grace, about disgraced former Gov. Jim McGreevey.

In 2015, Pelosi returned to her hometown to make a film about the tech boom's impact on The City. San Francisco 2.0 Variety called it "one of her finest."
