Infanta Maria Luisa of Spain (Spanish: María Luisa, German: Maria Ludovika) (24 November 1745 – 15 May 1792) was Holy Roman Empress, German Queen, Queen of Hungary and Bohemia, Grand Duchess of Tuscany as the spouse of Leopold II, Holy Roman Emperor.

Maria Luisa was born a Princess of Naples and Sicily. Her father, the future Charles III of Spain, had become King of Naples and Sicily in 1735 after its occupation by the Spanish in the War of Polish Succession. After her father became King of Spain at the death of her half-uncle, Ferdinand VI of Spain, in 1759, she became known as Infanta Maria Luisa of Spain. She still had the use of the style of Royal Highness.

Maria Luisa was born in Portici, in Campania, the site of the summer palace (Reggia di Portici) of her parents, King Charles, King of Naples and Sicily and Maria Amalia of Saxony. She was the fifth daughter, and second surviving child, of her parents. Her father became King of Spain as Charles III in 1759, and she moved with her family to Spain. Her first cousins included Louis XVI, Maria I of Portugal and Charles Emmanuel IV of Sardinia.

Maria Luisa was originally intended to marry the future Emperor Joseph II, but this was stopped by the discontent of Louis XV of France, who instead wished for Joseph to marry his granddaughter, Isabella of Parma.
