Maria Komnene (Greek: Μαρία Κομνηνή; c. 1154 – 1217), Latinized Comnena, was the queen of Jerusalem from 1167 until 1174 as the second wife of King Amalric. She occupied a central position in the Kingdom of Jerusalem for twenty years, earning a reputation for intrigue and ruthlessness.
Maria was a grandniece of Byzantine Emperor Manuel I Komnenos. Her marriage to Amalric in 1167 served to establish an alliance between the Byzantine Empire and the Kingdom of Jerusalem. When Amalric died in 1174, the crown passed to Maria's stepson, Baldwin IV, and she withdrew with her daughter, Isabella, to the city of Nablus, which she was to rule as queen dowager. Due to Baldwin's leprosy, Maria's stepdaughter, Sibylla, and daughter, Isabella, were regarded as potential successors. Maria married the lord of Ibelin, Balian, in 1177, and had four more children.
From 1180, Maria was one of the leaders of the faction opposing Sibylla and her husband Guy of Lusignan. Baldwin IV died in 1185, leaving Sibylla's son, Baldwin V, as king. When Baldwin V died the next year, Maria and her party planned to crown her daughter Isabella and son-in-law Humphrey IV of Toron, but Humphrey submitted to Sibylla and Guy, who thus solidified their hold on the kingdom. The Egyptian ruler Saladin invaded in 1187, capturing Jerusalem and most of the kingdom. Sibylla died in 1190 while Guy was retaking Acre, and his opponents asserted that his reign had thus ended and that Maria's daughter Isabella was the rightful heir. Maria had Isabella's marriage to Humphrey annulled so that the new queen could marry the more capable candidate, Conrad of Montferrat. Maria died in the reign of her great-granddaughter Isabella II, having outlived all her allies and adversaries.
