Louise of Savoy (Louise Christine; 1 August 1627 – 7 July 1689) was a Savoyard Princess by birth. She was the mother of Louis, Margrave of Baden-Baden, the famous chief commander of the Imperial army.

Louise was born at the Hôtel de Soissons in Paris. The Hôtel was the birthplace of her mother, a granddaughter of Louis de Bourbon, an uncle of Henry IV of France. Her father was Prince Thomas Francis of Savoy, the younger son of the Duke of Savoy and his Spanish wife, Infanta Catherine Michelle of Spain.

She married Margrave Ferdinand Maximilian of Baden-Baden (1625–1669) on 15 March 1653 at the Église Saint-Sulpice, Paris, France. The church was near the Hôtel de Soissons. The marriage contract was signed on the same day and is today preserved in the Parisian Institut de France. This marriage was negotiated by none other than the famous Cardinal Mazarin and the Ambassador of the Margrave of Baden-Baden one Monsieur Krebs. Her husband was the Hereditary Prince of Baden-Baden, this meant that he was the Heir apparent of his father Wilhelm, Margrave of Baden-Baden.

Marriages between German and Savoyard nobles were common in an era when many Savoyard nobles lived in German states notably Baden itself, due to official charges in the country.
