Dalam [[matematika]], '''Fungsi hipergeometris''' biasa atau Gaussia <sub>2</sub>''F''<sub>1</sub>(''a'',''b'';''c'';''z'') adalah sebuah [[fungsi istimewa]] yang diwakili oleh '''rangkaian hipergeometris''', yang meliputi sebagian besar fungsi istimewa lainnya sebagai [[kasus istimewa|kasus spesifik]] atau [[kasus pembatasan (matematika)|pembatasan]]. Fungsi tersebut adalah solusi dari [[persamaan diferensial biasa]] (ODE) [[fungsi linear|linear]] urutan kedua. Setiap ODE liberal urutan kedua dengan tiga [[titik tinggal reguler]] dapat bertransformasi menjadi persamaan tersebut.
