Year 1908 (MCMVIII) was a leap year starting on Wednesday (link will display the full calendar) of the Gregorian calendar and a leap year starting on Tuesday of the 13-day-slower Julian calendar.

Merkle's Boner refers to the notorious baserunning gaffe committed by rookie Fred Merkle of the New York Giants in a game against the Chicago Cubs in 1908. Merkle's failure to advance to second base on what should have been a game-winning hit led instead to a forceout at second and a tie game. The Cubs won the makeup game later, which proved decisive as they beat the Giants by one game to win the National League pennant in 1908. It has been described as "the most controversial game in baseball history."

1908 (MCMVIII) var ett skottår som började en onsdag i den gregorianska kalendern och ett skottår som började en tisdag i den 13 dagar långsammare julianska kalendern.
