A liquid-crystalline polyester production method with a shortened reaction time and improved productivity per unit time by using an organic basic compound containing one nitrogen atom in a molecule is achieved by a liquid-crystalline polyester production method comprising carrying out acylation reaction and/or ester-exchange in the presence of an organic basic compound containing one nitrogen atom in one molecule and satisfying the following inequality (1):

0A+0.4B   (1)

wherein, A and B satisfy A={(Ec^h+-Ec)/(Ep^h+-Ep)}-1 and B=(f/fp)-1; Ec denotes the heat of formation of the organic basic compound; Ec^h+ denotes the heat of formation of a compound coordinated by proton; Ep denotes the heat of formation of pyridine; and Ep^h+ denotes the heat of formation of pyridine coordinated by proton to the nitrogen atom; f and fp independently denote parameters relevant to the steric angles.
