Osgood is situated in Northern Darke County, and it is in the Marion Local School District. State Routes 705 and 716 intersect the town.

Osgood is named after Captain Osgood, the first settler. In 1881, Anne Brewer transferred seventy acres of land to Osgood, and the town was incorporated on August 6, 1883. Around the same time the Cincinnati-Hamilton and Dayton (C.H.D.) Railroad was built through the town, where the present day St. Rte. 716 is located. The town was built for a railroad depot. The depot and a water tower were completed in 1891.

The C.H. and D. was the major reason for growth of the town. Early businesses began to flourish. Among them were a grain elevator, barber shop, general store, hardware store, blackmith shop, saloon, electrician shop, shoemaker, livery stable, contractor, ditcher, grocer, sawmill, scrap yard, tile yard, piano store, bank, livestock yard, and a hotel. The early settlers were mainly of German and French decent. Many of the early settlers were farmers.

The town was served by several churches; The St. Nicholas Catholic Church, The Church of God, and The Osgood Christian Church. A Town Hall was used for a jail, a fire house, meetings, dances and medicine shows.

Present day Osgood has many new businesses and homes.
