Welcome to Delmar! On behalf of the residents of Delmar, we welcome you to our website. We invite you to explore our site and to visit the "Little Town Too Big For One State". You will find that we are a friendly little community unique in many ways.

Delmar straddles the Delaware and Maryland borders in southwest Delaware, making it a key point of the Mason-Dixon Line. Delmar is in both Sussex County Delaware and Wicomico County Maryland. Founded in 1859 as a Railroad town, we remain proud of our roots. We proudly display our 1929 Penna Railroad caboose and our 19th century highball, the last remaining in this country.

Recognized as the official beginning of the Mason-Dixon Line (1763-1767), the Cornerstone and Midpoint Marker of that famous survey is located just 6.5 miles west of town on Rt. 54. Set in 1768, this is the No.1 Marker of the "Mason Dixon Line". The Mason-Dixon line is a prominent historical fact in Delaware, since it forms the western and southern boundaries of the state. It wasn't until the Delaware Railroad reached the Maryland Border in 1859 that the town, one of the rare U.S communities divided by state lines, was born and named after its two mother states.
The founding of Delmar: 1859
The incorporation date of Delmar: 1899

While we still remain small in comparison to our neighboring towns, we are experiencing tremendous growth, both residentially and commercially. However, despite the growth, Delmar still has that small town appeal that only a small community can offer. Whether you are seeking a new place to call home or you are just passing through; we welcome you to our "Little Town".
