Nasser Saleh Al-Ghailani (Al-Gailani) is an Omani human rights defender and writer who has been actively involved in advocating for political reforms, freedom of expression, and the protection of civil liberties. He participated in the 2011 protests in Oman, part of the broader wave of demonstrations during the Arab Spring, which sought social, political, and economic reforms. On 11 June 2012, Al-Ghailani was arrested during a peaceful protest in Muscat alongside other human rights defenders. He was charged with offenses related to public assembly and blocking a road, which he and his colleagues denied. During his detention, he and other activists were reportedly denied access to legal counsel and were not afforded the opportunity to prepare a defense or review the evidence against them.  On 16 July 2012, the Court of First Instance in Muscat handed down prison sentences to several human rights defenders, including Al-Ghailani, for their participation in the protests. He was released on bail pending the appeal of his case. On 17 March 2013, following an appeal, Al-Ghailani and other defendants who had been accused solely of offenses relating to assembly were released on bail of 200 Omani Rials (around 520 dollars).
