1848 (MDCCCXLVIII) was a leap year starting on Saturday of the Gregorian calendar and a leap year starting on Thursday of the Julian calendar, the 1848th year of the Common Era (CE) and Anno Domini (AD) designations, the 848th year of the 2nd millennium, the 48th year of the 19th century, and the 9th year of the 1840s decade. As of the start of 1848, the Gregorian calendar was 12 days ahead of the Julian calendar, which remained in localized use until 1923.

1848 is historically famous for the wave of revolutions, a series of widespread struggles for more liberal governments, which broke out from Brazil to Hungary; although most failed in their immediate aims, they significantly altered the political and philosophical landscape and had major ramifications throughout the rest of the century.
