Agathis philippinensis (Almaciga or Dayungon) is a species of Agathis native to the Philippines, Sulawesi and Halmahera, where it occurs in upland tropical rainforest at 450-2,200 m altitude, rarely as low as 250 m in northern Luzon.

It is a large coniferous evergreen tree growing up to 65m tall with smooth, grey coloured bark. The leaves are oval, 4-6 cm long and 1.5-2 cm broad on adult trees, slightly larger, up to 7 cm long and 3 cm broad, on young trees. The seed cones are squat ovoid, 7-9 cm long and 12 cm diameter, containing numerous spirally arranged scales 28-32 mm long and 35-45 mm broad, each scale bearing a single winged seed. The pollen cones are 25-45 mm long and 10-11 mm broad.

It is the northernmost species of Agathis, occurring north to 19 N on the Philippine Calayan islands north of Luzon.
