伊斯坦布尔的Zui初名称为“拜占庭”（希腊语：Βυζάντιον），为约公元前660年墨伽拉殖民者建城时所取[a][1]。此名称被认为是来源于人名“拜占斯”，根据古希腊传统，此为殖民者的和传说中的一位王侯的名字。但现代学者亦认为“拜占斯”可能来源于色雷斯或伊利里亚，由此则要早于墨伽拉建城[20]。330年君士坦丁大帝将其定为罗马帝国的新东部首都，此地也开始被称作“君士坦丁堡”（拉丁语：Constantinopolis；古希腊语：Κωνσταντινούπολις），意为君士坦丁之城[1]。君士坦丁亦试图推广“新罗马”（拉丁语：NovaRoma；古希腊语：Νέα Ῥώμη）之名，但这一名称未获得广泛使用[21]。在西方，“君士坦丁堡”为此城Zui通常的称呼，直至土耳其共和国的建立；在奥斯曼帝国时期，“科斯坦丁尼耶”（奥斯曼土耳其语：قسطنطينيه）和“伊斯坦布尔”为通用名称[22]。即便如此，如今土耳其人认为将此时期（自15世纪中期始）的该城称为“君士坦丁堡”在政治上是不正确的，在历史上这并无错误[23]。
至19世纪，该城亦在外国人和土耳其人中有了一些其他的称呼。欧洲人将全城称作“君士坦丁堡”，但与土耳其人一同将金角湾和马尔马拉海间筑有城墙的半岛称作“士坦堡”[23]。“佩拉”（希腊语意“横跨”）亦被用于描述金角湾和博斯普鲁斯海峡间的地带，而土耳其人则称之为“贝伊奥卢”（土耳其语：Beyoğlu；此亦为今伊斯坦布尔一个区的正式名称）[24]。“伊斯兰堡”（意为伊斯兰之城）有时亦被用于称呼此城，甚至还被印刻于一些奥斯曼钱币之上[25]；有人认为这是今“伊斯坦布尔”的来源，但事实上“伊斯坦布尔”出现得要更早，甚至在奥斯曼帝国征服该城前即受到使用
