The Alliance of Democrats (AD) is a political party in Lesotho.
The party was established in December 2016 by Monyane Moleleki after he was suspended by the Democratic Congress party following a launched a failed leadership challenge against party leader and Prime Minister Pakalitha Mosisili. As well as Moleleki, several other MPs including Kabelo Mafura, Mokhele Moletsane, Tieho 'Mamasiane, Mokoto Hloaele, Ndiwuhleli Ndlomose and Kotiti Liholo defected from the Democratic Congress. The party supported a motion of no confidence in Mosisili in March 2017, which led to early elections in June. The AD received 7.3% of the vote, winning nine seats and becoming the fourth largest party in parliament. The party subsequently joined a coalition government led by Tom Thabane of the All Basotho Convention.
