Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The accompanying unaudited interim condensed Consolidated Financial Statements of Patriot National Bancorp, Inc. (the “Holding Company” or “PNBK”) and its wholly-owned subsidiaries, Patriot Bank, N.A. (the “Bank”) and PinPat Acquisition Corporation (collectively, the “Company” or “Patriot”), have been prepared in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and applicable Securities and Exchange Commission (“SEC”) rules and regulations. Accordingly, they do not include all of the information and footnote disclosures required by U.S. GAAP for complete annual financial statements. These unaudited interim condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included on the Annual Report on Form 10-K for the year ended December 31, 2025. The preparation of consolidated financial statements in accordance with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and to disclose contingent assets and liabilities. Actual results could differ from those estimates. Management has identified accounting for the allowance for credit losses, the analysis and valuation of its investment securities, the valuation of deferred tax assets, the valuation of derivatives, and the valuation of servicing assets as certain of Patriot’s more significant accounting policies and estimates, in that they are critical to the presentation of Patriot’s financial condition and results of operations. As they concern matters that are inherently uncertain, these estimates require management to make subjective and complex judgments in the preparation of Patriot’s consolidated financial statements. In the opinion of management, the accompanying unaudited interim condensed Consolidated Financial Statements reflect all adjustments necessary for a fair presentation of the financial position and results of operations for the interim periods presented. The results of operations for the three months and six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the remainder of 2026. Reclassification Certain prior-year amounts have been reclassified to conform to the current-year presentation
