Prince Adalbert Wilhelm Georg Ludwig of Bavaria (Munich, 19 July 1828 – Nymphenburg Palace, 21 September 1875) was the ninth child and fourth son of Ludwig I of Bavaria and Therese of Saxe-Hildburghausen.

In Madrid on 25 August 1856, he married Infanta Amalia of Spain (1834–1905), sister of King Consort Francis, Duke of Cádiz, sixth daughter and eleventh child of Infante Francisco de Paula of Spain (a younger son of King Charles IV of Spain) and Princess Luisa Carlotta of Bourbon-Two Sicilies.

They had five children: Prince Adalbert of Bavaria died on 21 September 1875 (the same day as his sister Alexandra) in Munich and is buried in the crypt of Michaelskirche in Munich, Bavaria.

It is often suggested that following his older brother Otto's death, Prince Adalbert became the heir presumptive to the throne of Greece.

Due to the renunciation of all the rights to the Greek succession by King Ludwig III, at Luitpold's death the rights to the throne of Greece were inherited by his second son, Prince Leopold.
