Lê Quốc Quân (born 13 September 1971) is a Vietnamese human rights lawyer, democracy activist and Catholic blogger.

He was arrested by the Vietnamese government on charges of tax evasion on 27 December 2012, convicted on 2 October 2013, and sentenced to 30 months in prison.

[1] The detention led U.S. presidential candidate John McCain and former Secretary of State Madeleine Albright to write to Vietnam in protest [2] and Amnesty International to name him a prisoner of conscience.

Ambassador Michael Marine invited his wife to tea at the U.S. Embassy, but was unable to meet her when police blocked her from entering.

He participated in a march of Catholics on 29 January 2008 at Saint Joseph Cathedral in Hanoi, protesting the government's occupation of land also claimed by the church.

[6] On 5 April 2011, he was re-arrested along with Phạm Hồng Sơn when attempting to observe the trial of democracy activist Cù Huy Hà Vũ.

[13] The police searched his office, confiscated documents and told his family that he will be charged under Article 161 of the Criminal Code relating to tax evasion.

[16] BBC News reported that the US government had been negotiating on Quân's behalf, and that "authorities may have been seeking a compromise so that his sentence was not long enough to upset Washington but sufficient to keep him behind bars.

It found that Quân had been targeted for his work as an activist and as a blogger and called for his immediate release or for his conviction to be reviewed by an independent court.

Prior to his release, a broad coalition of NGO's urged the Government of Viet Nam to respect his human rights, to reinstate his license to work as a lawyer, and to grant him reparation for the arbitrary detention he suffered.

[20] Following the 2007 arrest, U.S. presidential candidate John McCain and former Secretary of State Madeleine Albright expressed their support in freeing Quân.

[12] The organization also pointed out the similarity of using "tax evasion charges" to frame political dissidents such as in the case of Dieu Cay.

On 16 September 2014, L4L delivered an oral statement at the UN Human Rights Council, to once again demand attention for the situation of Quân.
