State Route 11 (SR 11) is a state highway in the U.S. state of Maine. It is a major interregional route which runs nearly the entire length of the state from south to north. The southern terminus of SR 11 is at the New Hampshire state line in Lebanon, where it connects to New Hampshire Route 11. The northern terminus is at U.S. Route 1 (US 1) and SR 161 in Fort Kent, near the Canada–US border. The highway travels through York, Cumberland, Androscoggin, Kennebec, Somerset, Waldo, Penobscot, Piscataquis and Aroostook counties. At 400.93 miles (645.23 km) in length, SR 11 is the longest state highway in Maine by a wide margin. However, it is not the longest numbered route in Maine, as US 1 runs for over 526 miles (847 km) in the state.

SR 11, together with NH 11 and Vermont Route 11, forms a continuous multi-state route across northern New England that stretches for over 550 miles (890 km) from Manchester, Vermont to Fort Kent, Maine.
