汴梁西瓜是開封的傳統特產，馳名古今，暢銷中外。其特點是：皮薄汁多，瓢沙脆甜，清利可口。民間素有"肖縣石榴碭山梨，汴梁西瓜紅到皮"之諺語。因開封古稱"汴梁"，萬事故開封一帶生產的西瓜都叫"汴梁西瓜"。
      
    西瓜原產于非洲熱帶沙漠地區，有四千多年的種植歷史。約于公元十世紀（五代十國時期）由西域移植我國，先在回鶻（現新疆境風）栽培，后傳入內地，因瓜種來自我國西部，故名西瓜。
      
    西瓜雙名寒瓜，為葫蘆科一年后草本植物。西瓜不僅是盛夏消暑解渴之上乘佳品，更兼有多種用途。其瓢、皮、籽均可入藥，有消煩止渴，解暑熱，寬中下氣，利小水，治血痢，解酒毒，治口瘡，清肺潤腸，補中宜人之醫療功用。西瓜皮還能做菜。
      
    汴梁西瓜在北宋種植已很普遍，在張擇端的《清明上河圖》上就有表現。開封一帶氣候溫和，夏季雨水均勻，沙壤土質較多，適宜西瓜的增長。加之開封人民長期以來積累豐富的西瓜種植經驗，把西瓜作為鄉土珍品精心種植，不斷改進，使開封西瓜逐漸成為中州著名的特產。
