Flores is one of the Lesser Sunda Islands, an island arc with an estimated area of 14,300 km² extending east from the Java island of Indonesia. The population was 1,831,000 in the 2010 census and the largest town is Maumere. Flores is Portuguese for "flowers".

Flores is located east of Sumbawa and Komodo and west of Lembata and the Alor Archipelago. To the southeast is Timor. To the south, across the Sumba strait, is Sumba and to the north, beyond the Flores Sea, is Sulawesi.

On 12 December 1992, an earthquake measuring 7.8 on the Richter scale occurred, killing 2,500 people in and around Maumere, including islands off the North coast.
