Almodis de la Marche (c. 1020-16 October 1071) was the daughter of Bernard I, Count of la Marche. She married Hugh V de Lusignan around 1038 and they had one son:

• Hugh VI de Lusignan (c. 1039-1101)

Almodis and Hugh of Lusignan divorced soon after the birth of their son, and she remarried to Count Pons of Toulouse by 1040. Together they produced several children, including:

• William IV of Toulouse
• Raymond IV of Toulouse
• Almodis of Toulouse, married Count Pierre of Melgueil

She was still Pons' wife in April 1053, but shortly thereafter Almodis was abducted by Ramon Berenguer I, Count of Barcelona. He kidnapped her from Narbonne with the aid of a fleet sent north by his ally, the Muslim emir of Tortosa. They married immediately (despite the fact both of her previous husbands were still alive) and they appear with their twin sons in a charter the next year. Ramon and Almodis were excommunicated for this illegal marriage until 1056. Together they produced four children:

• Berenguer Ramon II, Count of Barcelona
• Ramon Berenguer II, Count of Barcelona
• Inés of Barcelona, married Count Guigues I of Albon
• Sancha of Barcelona, married Count Guillermo Ramon I of Cerdagne

Ramon had a son from his previous marriage, Pedro Ramon, who was his heir. Pedro apparently resented Almodis' influence and was concerned she was trying to replace him with her own two sons. He murdered her in October 1071. Pedro was disinherited and exiled for his crime, and fled the country. When his father died in 1076, Barcelona was split between Berenguer Ramon and Ramon Berenguer, Almodis' sons. The family history of murder did not end with Pedro Ramon, as Berenguer Ramon earned his nickname "The Fratricide" when he killed his own twin brother.
