Erie Maritime Museum is a maritime museum located on Presque Isle Bay which rests on the waterfront in downtown Erie, Pennsylvania. It is managed by the Pennsylvania Historical and Museum Commission (PHMC). When it opened its doors on May 21, 1998, it became the first new Pennsylvania Historical and Museum Commission-affiliated museum in twenty years. Alongside its extensive indoor exhibits, it serves as the homeport for the US Brig Niagara, a modern recreation of the 1813-US Brig Niagara which served as Commodore Oliver Hazard Perry's relief flagship during the Battle of Lake Erie. While the museum focuses on the War of 1812 in the "frontier", it is designed to celebrate Erie's rich maritime heritage.
 The Erie Maritime Museum is administered by the Pennsylvania Historical and Museum Commission and is partnered with the Flagship Niagara League, a 501(c) non-profit, educational associate which is chartered by the PHMC to facilitate the brig Niagara.
 The Erie Maritime Museum is housed inside the former Penelec Front Street Station. From 1917 until the 1980s, the building was used to generate Erie, Pennsylvania's electricity and steam heat. Inside were five coal-fired steam generators. Remnants of Penelec's presence on the property can be found to this day. Visitors to the museum can view the original smoke stack which rests to the west of the parking lot. Additionally, once inside, guests are able to view a General Electric steam-powered generator and the station's original crane, which still works today.  When Penelec decided to shut down their Front Street operation, the goal was to tear down the structure. Plans changed after local officials convinced Penelec to save the building for future use.
 When the current version of the US Brig Niagara was completed in 1990, it needed a new home. In 1993, Niagara was berthed at the end of Holland Street, just to the east of its current location. Finally, in 1997 the Erie Maritime Museum began constructing its exhibits and displays. In May 1998, Niagara was moved to her current home and the Erie Maritime Museum opened its doors.
 The museum offers a wide range of multimedia and interactive exhibits coupled with interpretive programs that illustrate the region's maritime heritage. When in homeport, the Niagara herself is the major "exhibit". Berthed within yards of the museum, Niagara is visible from the building's bay side picture window. The present-day Niagara is a sail training vessel, meaning she is not always present at the museum for deck tours. Oftentimes during the warmer months, she can be found in ports across the Great Lakes.

 Julian Oliver Davidon's epic painting of the Battle of Lake Erie is on display on the main floor. The 54-by-102-inch (1,400 mm × 2,600 mm) masterpiece focuses on the climax of the Battle of Lake Erie. Painted from 1885–87, the artwork captures the Brig Niagara, "Crossing the T" and opening fire on both HMS Detroit and Queen Charlotte thereby leading to the British surrender at Put-In-Bay, the first time in world history that an entire British squadron surrendered to their enemy.
 The Battle of Lake Erie exhibit covers a thematic background, featuring information about the issues behind the War of 1812, size differences between the American, British, and Canadian forces, Uniforms, and why Erie, Pennsylvania was chosen for building the American Great Lakes fleet.
 The centerpiece exhibit on the first floor of the museum features a reconstruction of the midships section of USS Lawrence. The replicated Lawrence, Commodore Oliver Hazard Perry's first flagship during the Battle of Lake Erie, comes complete with mast, spars and rigging to foster hands-on learning in the ways of sail handling. Another display is the adjoining section of the Lawrence' replica that has been blasted with live ammunition from the current Niagara's own carronades at the National Guard training facility in Fort Indiantown Gap, near Harrisburg. This "live fire" exhibit of Lawrence recreates the carnage inflicted upon both ships and men during the Battle of Lake Erie and throughout the Age of Fighting Sail.
 Fighting Sail presents a life size upper-portion of a working mast taken directly from Niagara. This exhibit focuses on the construction of wooden sailing vessels, shipboard life, 19th Century Navy medicine, a gun deck recreation from  Lawrence, building tools, knots, and more.
