介紹信是社交書信中較常用的，一般是向收信人介紹第三者并希望得到他的支持、幫助或者照顧。根據介紹人、被介紹人與收信人之間的關系以及介紹的目的，可以分為普通社交介紹信和公務介紹信兩種。

　　公務介紹信往往比較正式，有一定的規律可循。介紹信一般都包括：第一部分詳細敘述被介紹人的情況，如姓名、年齡、學歷等;第二部分說明情由，即被介紹人此行的目的;第三部分寫明被介紹人希望得到哪方面的幫助并向收信人致謝。

　　介紹信寫作三步曲：

　　說明被介紹人的身份提出希望收信人做的事情像收信人表示感謝或者表示希望能合作愉快。

　　注意：

　　語言上介紹信應措辭禮貌得體，對被介紹人的說明應簡潔明了、重點突出。
