ঐতরেয় আরণ্যক গ্রন্থে সর্বপ্রথম 'বঙ্গ' শব্দের উল্লেখ পাওয়া যায়। প্রাচীন শিলালিপিতে বঙ্গের দু'টি অঞ্চলের নাম পাওয়া যায়। একটি বিক্রমপুর এবং অন্যটি নাব্য (নিচু জলাভূমি) এর সীমানা ছিল ঢাকা, গাজীপুর, ফরিদপুর, খুলনা, বরিশাল, বাগেরহাট, পটুয়াখালী। দেশবাচক বাংলা শব্দের প্রথম ব্যবহার হয় আবুল ফজলের আইন-ই-আকবরি আছে। গঙ্গা ও ভাগীরথীর মাঝখানের অঞ্চলকে বলা হতো বঙ্গ। প্রাচীন বঙ্গ দেশের সীমানার উল্লেখ পাওয়া যায় ড. নীহাররঞ্জন রায়ের "বাঙ্গালির ইতিহাস" নামক গ্রন্থে।
