Chronology
Predecessor	New Flyer High Floor
Successor	New Flyer Invero New Flyer Xcelsior

The New Flyer Low Floor is a line of low-floor transit buses that was manufactured by New Flyer Industries between 1991 and 2014. It was available in 30-foot rigid, 35-foot rigid, 40-foot rigid, and 60-foot articulated lengths. In addition to the different available lengths, the buses were sold with a variety of prime movers, ranging from conventional diesel and CNG combustion engines to diesel-electric hybrid, gasoline hybrid, and hydrogen fuel cell.

The New Flyer Low Floor was restyled in 2005, resulting in two distinct variants: the Low Floor Restyled (LFR), which largely replaced the conventional Low Floor for transit service, and the Low Floor Advanced (LFA), which was intended for bus rapid transit service. New Flyer introduced the Invero in 1999 with the intent that it would replace the Low Floor line, but few were sold; in 2008, New Flyer introduced the Xcelsior, and the Low Floor line was discontinued by 2014.
