If you are shopping an SBA 7(a) or conventional commercial loan in Maine, the bank you call first matters more than most borrowers think. A lender that already writes a lot of commercial credit and sits in your state is structurally likelier to say yes than a national name passing through. This page ranks the Maine-headquartered banks doing the most commercial lending right now, using public Q1 2026 FFIEC call-report data. It is the open-book version of what the paid report does with far more inputs.
Maine's banking map is short and old, a few savings-bank descendants and community lenders covering a rural state most national banks never bothered to enter.

C&I lending muscle, ranked
Commercial and industrial loans outstanding for the top 10 Maine-HQ lenders, Q1 2026. This is the single number our ranking leans on hardest.
How we ranked these
Three steps, all of them transparent. First, we took every bank headquartered in Maine. Second, we loosened the usual 10 percent C&I cutoff to 5 percent here, because Maine has a shallow commercial-banking bench and a stricter filter would leave too short a list (a bank that is 90 percent home mortgages is not your SBA lender, regardless of size). Of the qualifying banks, 17 cleared that bar. Third, we ranked them by C&I loan dollars outstanding, which already blends balance-sheet size with how committed a bank is to commercial credit, and kept the top 15.
This is an honest, simplified proxy. It does not see a bank's actual SBA 7(a) origination volume (that lives in SBA FOIA data, not the call report), its appetite for your industry, or whether it funded forty SBA loans last quarter or zero. The $49 Borrower Assist report folds all of that in and ranks against your specific deal, not just your state. That is the part worth paying for.
What Maine looks like for a borrower
Maine's banking map is short and old, a few savings-bank descendants and community lenders covering a rural state most national banks never bothered to enter.
On the numbers: Maine's 22 headquartered banks carry $48.0B in assets between them, the largest being Bangor Savings Bank of Bangor at $7.4B. The median bank keeps 6.8% of its loan book in C&I credit, which is the pool the table below ranks.
None of that tells you which of these banks will fund your specific deal. A $400,000 restaurant acquisition and a $4M owner-occupied warehouse purchase have different optimal lender lists even in the same state, and the ranking above does not split by loan size, industry, or collateral. Treat it as your starting shortlist, not your final answer.
How to use this list
- Start with the bank near you that has the strongest commercial profile, not just the closest branch. A lender with a real C&I book understands your deal faster.
- Ask for the SBA or commercial lending group directly. The general line routes business deals slowly.
- Have a one-page summary ready: use of funds, cash flow, collateral, owner credit, timeline. Banks decide whether to engage in the first ninety seconds.
- Run two banks in parallel, not five. Two real conversations close a loan; five waste everyone's time.
