[Objectives] Addressing the challenges of weak generalization and heavy reliance on large amounts of city-specific annotated data in environment-dependent crime spatio-temporal prediction, this paper proposes a foundation model named ST-Crime based on generative pre-training and prompt learning, aiming to enhance the accuracy of environment-dependent crime spatio-temporal prediction and improve generalization performance in new environments. [Methods] The method first unifies crime data into a tensor representation, employs a Transformer backbone to capture global spatio-temporal dependencies, and introduces a crime spatio-temporal memory retrieval enhancement module. This module extracts common spatio-temporal patterns from multi-city data and generates prompt information through spatio-temporal memory, crime-type interaction, and adaptive graph learning mechanisms to strengthen the model's expressive capability. [Results] Experiments were conducted using crime data from the year 2019 across four cities—New York, Los Angeles, San Francisco, and Chicago—totaling over 300 000 records and covering four typical environment-dependent crime types: burglary, robbery, felony assault, and grand larceny. In the full-training scenario (using year-long data from New York, Los Angeles, and San Francisco), ST-Crime achieved Macro-F1 scores of 0.739 7, 0.643 3, and 0.665 2, and Micro-F1 scores of 0.687 1, 0.601 8, and 0.537 5 on the three cities respectively, significantly outperforming existing baseline models.Compared to the best-performing baseline model in each city, it achieved improvements of 1.57%, 4.30%, 6.45% in Macro-F1, and 1.15%, 6.06%, 9.63% in Micro-F1, demonstrating significant advancements. For Chicago in the few-shot (fine-tuned with only 20% of data) and zero-shot (direct inference) scenarios, it also achieved Macro-F1 scores of 0.658 6 and 0.603 1, and Micro-F1 scores of 0.596 9 and 0.565 3, which surpassed the best baseline by 7.02%, 7.73% in Macro-F1, and by
