Firstly the title of Bhagavad Gita is two Sanskrit words. Bhagavad comes from the word Bhagavan which referrers to the Supreme Personality of Godhead and 'gita' means song. Sometimes we hear the Gita referred to in English as "The Song of God," and this is a reasonable English translation of the title and it is a fairly accurate description of what the Bhagavad Gita is.
The Bhagavad Gita was spoken by Krishna, the Supreme Personality of Godhead, to His friend Arjuna on the battlefield of Kuruk
