中唐时代文学名家辈出，韩愈作为中唐文学中重要代表人物，其与同时期文人的交游情况十分值得注意。前人对这一问题虽有关注，但多只局限于个别诗文名家，且对韩愈的整体交游网络缺乏全面且系统的整理。本文针对前人研究的不足，试图更为全面且系统地对韩愈的交游活动进行整理与分析。本文以韩愈的仕宦经历为依据，将韩愈的一生分为求举时期、藩镇幕府时期、仕途起步期、仕途上升期四个基本时期，并以此为基础对韩愈的交游活动进行了考察。文章搜集了韩愈诗文集中出现次数较为频繁的90余主要交游人物，以交往的开始时间为顺序编入四个时期内，对其履历及与韩愈的交游活动进行了系统整理与详细考述。而在每个时期内部，又以交游性质为根据，对韩愈的交游对象进一步划分为公卿同僚、交游核心层、其他特殊的交游群体等，分别予以考察。另外，在史实考证的基础上，针对韩愈交游活动中的存在的众多争议性话题，本文也做了总结与辨析。
