Poverty is closely related to food security because poor people have limited consumption choice including that of food. This study aims to examine poverty line and correlation between poverty and food security in Aceh Province. This study utilized a panel data from 23 regencies/municipalities in Aceh Province during the period of 2007-2013. To measure poverty line, approaches taken were minimum physical need based on minimum expenditure level of rice consumption and food security based on energy consumption. Data were analyzed using a 2SLS method. The result shows that the regions with low poverty line have lower energy consumption compared to those with higher poverty line. Banda Aceh has the highest poverty line and energy consumption level. On the other hand, North Aceh, Southeast Aceh, Bener Meriah Regencies, and Subulussalam Municipality are the regions areas with lowest poverty lines and energy consumption levels. To improve food security, some measures to take are food availability assurance, farmers' empowerment, agricultural inputs subsidy provision, infrastructure construction, paddy field leveling-up, agricultural extension improvement, innovation invention, and food warehouse establishment.
