Guttenberg is a city in Clayton County, Iowa, United States, along the Mississippi River. The population was 1,817 at the time of the 2020 census, down from 1,987 at the 2000 census.

History 
Prairie La Porte, meaning "the door to the prairie," was the first name given to Guttenberg by French explorers in 1673. The Guttenberg area was a site of Sac and Fox campgrounds until 1823. The Louisiana Purchase of 1803 transferred ownership to the United States and the Black Hawk Purchase of 1833 finally opened the area for legal settlement.

Guttenberg's past is preserved today in the many limestone buildings built by German immigrants in the mid-to-late 19th century. These structures were used for both residential and commercial purposes. Many such as the Albertus Building are pre-Civil War era and are preserved in the Front Street Historic District.
   
Guttenberg's riverfront location was pivotal in its early commercial development. The town first served as a focal point for westward settlement and as an early governmental and administrative center. It was the early location of the county seat from 1838 to 1843. Guttenberg served as a supply center for the general area until the Civil War, when railroads and an interior road system combined to detract from Guttenberg's role as a market center.

The earliest businesses included general supply stores, blacksmith, wagon shops, and hotels. The loss of the county seat in 1843 slowed growth and the population declined. Economic revival began in 1845 with the influx of hundreds of German immigrants under the auspices of the Western Settlement Society of Cincinnati and continued with the development of the lead mining industry along Miners Creek.

The German immigration began in 1845, and by 1850 the town was sizable and nearly all German. The city takes its name from Johannes Gutenberg, the inventor of movable type. Many of the town's streets are named for 18th & 19th century German writers, poets, playwrights and philosophers such as Koerner, Herman, Weiland, Lessing, Schiller, Herder and Goethe, whose writings became prolific in Germany because of Johannes Gutenberg's invention. A replica of a Bible Gutenberg printed is on display at the public library.

Guttenberg incorporated in 1851. The influence of the German population was best indicated by the construction during the period between 1845 and 1865 for over one hundred stone buildings. The bluff limestone was easily obtained and good, local clay and lime for construction was available. Four large riverside warehouses opened and a large flour mill, stores, and hotels appeared during this period. The steamboat trade deposited merchandise and picked up farm produce, milled flour and lead ore.

Guttenberg experienced many floods, the most recent and devastating being in 1965, after which a levee was built. Today, Guttenberg's population is 1,817 and it is the largest town in Clayton County.
