Harvest is an unincorporated community and census-designated place (CDP) in the northwestern part of Madison County, Alabama, United States, and is included in the Huntsville-Decatur Combined Statistical Area.

[3] From the late 1800s through the early 1900s, Harvest saw growth and development resulting from the construction and operation of a rail line southward from Fayetteville, Tennessee.

The Nashville, Chattanooga & St. Louis (NC&StL) Railway eventually acquired the rail line.

In the early-to-mid-1900s, Harvest was centered around the railroad between the communities of Capshaw (the line's terminus) and Toney.

In 1929, the NC&StL abandoned the line, pulled up the rails and transferred the right-of-way to the Madison County Highway Department with a quitclaim deed.

Today, that roadbed is a two-lane roadway that continues to serve as a vital link in the modern day-to-day transportation network, and carries the appropriate name, “Old Railroad Bed Road.” On April 3, 1974, during the 1974 Super Outbreak, two F5 tornadoes struck the community within 30 minutes of each other.

Most of Harvest, primarily along the Old Railroad Bed Road area, and other nearby communities, including Tanner, was destroyed.

Harvest was hit by another violent tornado on May 18, 1995, that devastated the Anderson Hills subdivision.

On April 27, 2011, during the 2011 Super Outbreak, Harvest suffered significant damage from the EF5 tornado that destroyed the towns of Hackleburg and Phil Campbell, primarily north of Nick Davis Road, situated between Old Railroad Bed Road and Wall Triana Highway.

[4] According to the U.S. Census Bureau, the community has a total area of 12.4 square miles (32 km2), all land.

The top of this small mountain is the site of several substantial communications towers used by local radio stations.

As of the 2020 United States census, there were 5,893 people, 2,043 households, and 1,642 families residing in the CDP.

The Madison County Sheriff's Department administers law and order in Harvest.

The Harvest Volunteer Fire Department consists of approximately 40 members serving the residents of West Central Madison County.

The 2021 opening of the nearby $2.3 billion Mazda Toyota Manufacturing plant will create up to 4,000 jobs, according to the company.
