Louise Adélaïde de Bourbon (2 November 1696 – 20 November 1750) was a French princess of the Blood and member of the courts of Louis XIV and his successor Louis XV of France. She never married, but she had many illegitimate children.

Born at the Hôtel de Conti in Paris Louise Adélaïde was the youngest surviving daughter of François Louis, Prince of Conti and his wife Marie Thérèse de Bourbon. From birth, Louise Adélaïde was known by her style of Mademoiselle de La Roche-sur-Yon. Her oldest sister was Marie Anne de Bourbon (1689–1720), future Princess of Condé; her oldest surviving brother was Louis Armand de Bourbon, the future Prince of Conti.

The year after her birth, her father was made the Titular King of Poland by Louis XIV but later declined the offer due to his affections for the Duchess of Bourbon, his mistress and daughter of the king.On 16 February 1707 she was baptised in the Royal Chapel of Versailles and named in honour of Louis, Grand Dauphin and Marie Adélaïde, Duchess of Burgundy.

In 1709, Mademoiselle de La Roche-sur-Yon lost her father and her brother succeeded as Prince of Conti. Her older sister married in 1713 at the age of 24; the groom was her maternal cousin Louis Henri, Duke of Bourbon.

Louise Adélaïde never married, although in 1748, a marriage was projected with Stanisław I Leszczyński, former King of Poland
