The increased use of social media and the internet is leading to an increase in cyberbully vulnerabilities as well as daily usage. Cyberbullying is a deliberate, aggressive behavior that can be committed by an individual or organization. It occurs when people communicate, post, and distribute damaging, false, or unfavorable content online. For individuals impacted, it results in emotional and mental health issues. Therefore, it is imperative to create automated techniques for the detection and prevention of cyberbullying. The majority of the research done on cyberbullying detection in recent years has been on text-based analysis. The two most significant media in incidents of cyberbullying are text and visual. This paper presents An Explainable Multimodal Deep Learning Model for Cyberbullying Detection include three steps The first step involves collecting datasets from different resources, which include images and their captions with binary classes (bullying and non-bullying). The second step applies two techniques of XAI: CNN+GradCam to analyze input images and produce visual explanations, and LSTM+LRP to analyze and interpret input text. The third step employs two techniques of data fusion (early and late). Final step represents the evaluation performance of the EMDL-CBD model based on a set of accuracy metrics
