Our History

The state of Maryland earned her nickname the “Old Line State” in 1776 during the first major battle of the Revolutionary War. If not for the “Maryland 400″ who sacrificed their lives and allowed the Continental Army to escape, the war would’ve ended that day. Maryland’s regiment of soldiers, referred to as the “Old Line,” achieved a reputation as saviors of the cause of independence. As a tribute to those brave Maryland men, Old Line Bank proudly chose its name.

Experience is Our Best Asset

Old Line Bank is a State Chartered banking association organized under the laws of the State of Maryland. The Bank was founded in 1989 originally as a National Bank under the name Old Line National Bank. On June 28, 2002, we converted to our current Maryland charter. We conduct general banking business, consisting of granting secured and unsecured commercial and consumer loans, construction financing and mortgages; checking services and interest-bearing demand, savings and time deposit services.

Having started 30 years ago with one branch in beautiful southern Maryland, Old Line Bank withstood the tests of a down market and rose to be a financial partner of choice in the State of Maryland. With over $3.1 Billion in Assets and locations that wrap around both the Baltimore and Washington corridors, Old Line Bank knows the market and having a locally based team helps us dedicate our efforts solely to the area.

We are proud to say that our customers have grown with us and this holds true to our philosophy of partnership, where we play a role in development and prosperity of our great region. Customers choose Old Line Bank because the bank is here for the long haul; we will be your local financial advocate. With us on your side as a banking partner, you will have an ally with the expertise to guide you through all the turns of our market. Let us show you how our experience can be your best asset!
