Niccolò di Pietro Gerini (c. 1340 – 1414) was an Italian painter of the late Gothic period, active mainly in his native Florence although he also carried out commissions in Pisa and Prato.

As is typical for Gothic depictions, Gerini's figures have large chins, sloping foreheads, and sharp noses whilst their bodies are squat and frontally displaced.

Gerini is recorded as collaborating with Jacopo di Cione on frescoes for the Guild hall of the Judges and Notaries in Florence in 1366.

He is the Niccolaio Dipintore who worked with Jacopo di Cione on the altarpiece of the Coronation of the Virgin[2] commissioned by the Albizzi family for San Pier Maggiore, Florence in 1370.

Between 1391 and 1392 he worked in Prato where he frescoed Palazzo Datini and the Church of San Francesco with Lorenzo di Niccolò and Agnolo Gaddi.
