Oakdale Manor, Historic plantation house in Howard County, United States.

Oakdale Manor is a brick plantation house in Howard County featuring Federal and Colonial Revival architecture with over twenty rooms. Today the property serves as a venue for events and has a winery operation on its grounds.

The land was surveyed in 1765 as "Fredericks Burgh" and patented by Henry Griffith. Albert Galltin Warfield built the house in 1838; Edwin Warfield moved in in 1891 after his father's death and enlarged it to more than twenty rooms. He became governor of Maryland in 1904, and in 1907 hosted National Guard troops under Adjutant-General Clinton L. Riggs. His grandson Edwin Warfield III sold the manor in the mid-1970s.

Oakdale was the site of a reunion of Company A, a Confederate unit Edwin Warfield had served with. The grounds also hold a pre-1838 log slave quarters, a tenant house, a carriage house, a smokehouse, a barn and an octagonal glass greenhouse, so a walk here reads as a working plantation layout rather than a single house.

The property is best explored on foot as the various buildings and structures are spread across the grounds. Visitors should wear comfortable shoes and allow time to walk around the entire estate and see all areas.

Oakdale's land was first surveyed on 16 February 1765 by William Shipley and patented as "Fredericks Burgh" by Henry Griffith that March, before being repatented as "Addition to Part of Fredericks Borough". The 1838 house was built by Albert Galltin Warfield, great-grandson of Captain Benjamin Warfield of Cherry Grove. The estate also hosted a reunion of Company A, in which Edwin Warfield had served.
