Green synthesis of Ag
2
O nanoparticle (Ag
2
O NP) has been investigated using Vernonia amygdalina Del. leaf extract (VaDLE). The secondary metabolite of VaDLE plays a role as a base source and capping agents, which can be determined by phytochemical screening. The diffraction pattern and crystallinity of Ag
2
O NP was confirmed by X-ray diffraction, while the distribution size of Ag
2
O NP can be determined by using transmission electron microscopy. Fourier transform-infra red spectrum was used to show the interaction VaDLE and Ag
2
O NP. FT-IR characterization showed the presence of Ag-O band at 825 cm
-1
. The characterization of UV-Vis spectrophotometer showed the typical absorption of Ag
2
O at maximum wavelength, λ
max
of 262 and 452 nm. The size distribution of Ag
2
O was 22.70 nm confirmed by particle size analyser. UV-Vis DRS characterization proved the bandgap energy of Ag
2
O at 1.56 eV. The photocatalytic activity of Ag
2
O NP was observed on the degradation of methylene blue. The result of the degradation percentage was 71.59%.
