[4] Olivette was settled in the mid-19th century as a small farming community along an old Indian trail originally called the Bonhomme Road (now known as Old Bonhomme, which meets and essentially turns into Olive Boulevard).

The first brick schoolhouse in St. Louis County was built in the 1850s at the corner of Price and Old Bonhomme in Olivette.

Logos High School is built on the former grounds of the schoolhouse.

The reservoir was built at Brock's Pond, a local recreational spot, and finished in 1926.

[5] Olivette was incorporated in 1930 by combining the communities of Central, Tower Hill, Olive, and Stratmann.

In fact, Price Road and Olive Boulevard intersect at the exact midpoint between the Port of St. Louis on the Mississippi River and Howell's Landing on the Missouri River.

According to the United States Census Bureau, the city has a total area of 2.78 square miles (7.20 km2), all land.

Olivette's neighbors include Overland and unincorporated St. Louis County to the north, Creve Coeur to the west, Ladue to the south, and University City to the east.

The Monsanto Corporation used to be located partially in Olivette until it was acquired by Bayer in 2018.

The 2020 United States census[9] counted 8,504 people, 3,114 households, and 2,213 families in Olivette.
