Margaret of Bar (1220–1275) was a daughter ofHenry II of Bar andPhilippa of Dreux.^[1] She was Countess ofLuxembourg by her marriage toHenry V of Luxembourg. She is also known asMarguerite of Bar.

Margaret's maternal grandparents wereRobert II of Dreux (whose paternal grandfather was KingLouis VI of France) and his second wife Yolanda de Coucy. Her paternal grandparents wereTheobald I of Bar and his second wife Ermesinde of Brienne.

Margaret was the eldest of seven children born to her parents. Her brother wasTheobald II of Bar. Margaret's sister, Jeanne married Frédéric de Blamont. The rest of her siblings died young or unmarried.

In 1240, Margaret marriedHenry V of Luxembourg.^[2] Margaret was twenty years old, and Henry was twenty-four.

Margaret brought HenryLigny-en-Barrois as herdowry, however, by a clause in the marriage contract, it remained under the feudal suzerainty of thecounty of Bar. In contempt of this, Henry paid homage in 1256 toTheobald II of Navarre, in his capacity asCount of Champagne. Margaret's brother,Theobald II of Bar, took advantage of the conflict then raging betweenFrederick III of Lorraine (their cousin) and thebishops of Metz. Henry V was a partisan of the duke and so Theobald took the side of the bishop. Henry was captured in battle atPrény on 14 September 1266. On 8 September 1268,King Louis IX arbitrated between the two counts and Henry was freed and repossessed of Ligny, but under the suzerainty of the Barrois.

Margaret and Henry had seven children:

• Henry VI (died 1288), Count of Luxembourg
• Waleran I (died 1288), Count of Ligny & Roussy^[3]
• Isabelle (1247–1298), marriedGuy of Dampierre
• Philippa (1252–1311), marriedJohn II, Count of Holland^[4]
• Margaret
• Felicitas
• Joanna (died 1310), Abbess ofClairefontaine

Margaret and Henry made peace withGuy of Dampierre by marrying him to their daughter,Isabelle. Their other daughter,Philippa marriedJohn II, Count of Holland and became grandparents toPhilippa, Queen of England andMargaret II, Countess of Hainault.

Margaret died in 1275, six years before her husband's death.
