Larisa Iosifovna Bogoraz (August 8, 1929 - April 6, 2004) was a dissident in the Soviet Union (now Russia).

She was born into a family of Communist Party bureaucrats. She graduated as a linguist from Kharkov University in the Ukraine, and in 1950, married her first husband, Yulii Daniel , a writer. Together, they moved to Moscow.

Her marriage to Daniel would ultimately lead to her becoming involved in activism. In 1965, Daniel and a friend of his, Andrei Sinyavsky, were arrested for a number of anti-Soviet writings that they had had published overseas under pseudonyms. The trial of the two men was the beginning of a crackdown on dissent under General Secretary Leonid Brezhnev. They were both sent to terms in forced labor camps. After their detention, Bogoraz wrote to Brezhnev in protest, despite knowing that such an act could land her in prison.

Bogoraz rose to notoriety when, on August 25, 1968, she was one of seven people to protest in Red Square against the Soviet Union's invasion of Czechoslovakia. For this, she was arrested, tried and sentenced to four years of exile in Siberia, which she spent in a woodworking plant.

Daniel was released in 1970, while Bogoraz was still in Siberia. Their marriage did not survive much longer, and they soon divorced. However, soon after her release, Bogoraz resumed her resistance of the Soviet regime. She signed many public appeals to the authorities. She co-wrote an underground book, Memory, which detailed Stalin's terror and was subsequently published overseas. She also contributed to the underground publication Chronicle of Current Events. In 1975, she wrote a letter to Yuri Andropov, who was the head of the KGB at the time, requesting that he open the organization's archives.

She married again to another prominent dissident, Anatoly Marchenko . Together, they co-wrote a number of appeals. However, he was arrested in 1980, and unlike Daniel, did not survive his sentence. Bogoraz launched a campaign in 1986 to have all political prisoners freed. The campaign was successful, as the following year, General Secretary Mikhail Gorbachev began releasing them. This came too late for Marchenko, who died as a result of a hunger strike shortly before the initial release.

In 1989, Bogoraz joined, and subsequently became chairwoman of, the newly re-founded Moscow Helsinki Group. She acted as a bridge between the old guard of dissidents, and the new generation that were arising as the Soviet Union collapsed.

After the demise of the Soviet Union, Bogoraz continued her activism, visiting prisoners and holding seminars on the defence of human rights. She also became chairwoman of the Seminar on Human Rights, a joint Russian-American nongovernmental organization. She resigned from the latter in 1996, but continued to exert influence in human rights circles up until her death.

Not long before her death, she issued an open letter condemning the 2003 invasion of Iraq. She died on April 6, 2004, aged 74, after a series of strokes.
