Peosta is a city in Dubuque County, Iowa, United States, and an exburb of the city of Dubuque. It is part of the Dubuque, Iowa Metropolitan Statistical Area. The population was 651 at the 2000 census, but in 2007 its population was estimated to be 1,129. Peosta is the seventh-largest city in Dubuque County, but it will likely soon pass Farley, and Epworth to become the fifth-largest. The community is home to a large industrial park, the largest campus of Northeast Iowa Community College, and a handful of new commercial businesses. However, the city is increasingly becoming a bedroom community, much like nearby Asbury, made up of spacious new subdivisions.
Peosta has experienced a 72.6% increase in population from 2000 to 2007, making it the state's 6th-fastest growing city (with 1,000 people or more) during that period.
For most of its history, and even as recently as 1990, Peosta was a quiet rural town of around 100 people. The groundwork for later growth was laid in the 1960s, when the new 4-lane U.S. Highway 20 opened along the city's southern edge, providing quick access to Dubuque. The city was also aided by the opening of Northeast Iowa Technical Institute (later NICC) in 1979. However, it wasn't until the city's industrial park began to flourish in the 1990s that the population began to soar. Peosta grew from a tiny 128 people in 1990 to over 1,000 today, and it continues to climb rapidly. This 820% growth in 16 years has helped attract new businesses and services to Peosta as well. The city now boasts two elementary schools, its own community center, hotel, church, industrial park, and expanding neighborhoods.
In the Iowa General Assembly, Peosta is represented by Senator Tom Hancock (D-Epworth) in the Iowa Senate, and Representative Ray Zirkelbach (D-Monticello) in the Iowa House of Representatives.

Peosta, and all of Iowa, are represented by U.S. Senators Chuck Grassley (R) and Tom Harkin (D).
