Odo, count of Paris, is crowned king of West Francia (France) by Archbishop Walter of Sens at Compiègne.

Year 888 (DCCCLXXXVIII) was a leap year starting on Monday of the Julian calendar.

Odo was King of West Francia from 888 to 898. He was the first king from the Robertian dynasty, the parent house of the House of Capet. Before assuming the kingship, Odo was the Count of Paris, since 882. His reign marked the definitive separation of West Francia from the Carolingian Empire, which would never be reunited.

Count of Paris was a title for the local magnate of the district around Paris in Carolingian times. After Hugh Capet was elected King of the Franks in 987, the title merged into the crown and fell into disuse. However, it was later revived by the Orléanist pretenders to the French throne in an attempt to evoke the legacy of Capet and his dynasty.

In medieval historiography, West Francia or the Kingdom of the West Franks constitutes the initial stage of the Kingdom of France and extends from the year 843, from the Treaty of Verdun, to 987, the beginning of the Capetian dynasty. It was created from the division of the Carolingian Empire following the death of Louis the Pious, with its neighbor East Francia eventually evolving into the Kingdom of Germany.

Walter was Archbishop of Sens from 887 to 923.
