Exploring the changes in extreme precipitation events in this region under the background of global warming is of great significance for ensuring regional ecological security and disaster prevention and reduction. This article is based on daily precipitation observation data from meteorological stations from 1961 to 2020. After data screening, quality testing, and outlier removal, 10 extreme precipitation indices were selected and calculated. The extreme precipitation index dataset for the upper and middle reaches of the Yellow River was obtained by time period and regional statistics. After quality control measures such as unit conversion, removal of missing data sites, interpolation of missing values, and data validation on time series and spatial patterns, the dataset has high accuracy and reliability. This dataset can be used to analyze the spatiotemporal characteristics of extreme precipitation events in the upper and middle reaches of the Yellow River and their response to climate change. It can also provide basic data support for evaluating water resource security and the risk of droughts and floods in the region
