Qian Weidao (騫味道) (died January 11, 689) was a Chinese politician who served twice as a chancellor of the Chinese Tang dynasty, during the first reign of Emperor Ruizong.

Little is known about Qian Weidao's career before his first stint as chancellor, as, atypical for a chancellor, he did not have a biography in either the Old Book of Tang or the New Book of Tang. It is, however, known that his family was from Jincheng (金城, in modern Lanzhou, Gansu). As of 684, he was serving as imperial censor reviewing central government affairs (左肅政大夫), when he and his subordinate, Yu Chengye (魚承曄), was put in charge by Emperor Ruizong's powerful mother and regent Empress Dowager Wu (later known as Wu Zetian) of investigating and interrogating the chancellor Pei Yan after accusations of treason, as Pei had angered her by suggesting that she return imperial authority to Emperor Ruizong. Many officials spoke on Pei's behalf, but Empress Dowager Wu reacted by arresting and demoting them, while promoting Qian and an official who had testified that Pei had committed treason, Li Jingchen, to be chancellors—in Qian's case, with the designation Tong Fengge Luantai Sanpin (同鳳閣鸞臺三品), a greater designation than Li's Tong Fengge Luantai Pingzhangshi (同鳳閣鸞臺平章事) designation. She also made him acting Neishi (內史) -- the head of the legislative bureau of government (鳳閣, Fengge) and a post considered one for a chancellor.

In 685, there was an incident that made Empress Dowager Wu demote Qian. At that time, the official Fang Xianmin (房先敏) was demoted, and he met the chancellors to complain about the demotion. Qian told Fang, "This was the Empress Dowager's decision." Another chancellor, Liu Yizhi, instead stated, "You were dragged into this because of another's fault, and your demotion was based on the decision of the officials." These words were reported to Empress Dowager Wu, and she was displeased that Qian blamed her and pleased that Liu did not, and she demoted Qian to be the prefect of Qing Prefecture (青州, roughly modern Weifang, Shandong) while promoting Liu.

By 688, Qian was again the imperial censor reviewing central government affairs. Winter of that year, he was made chancellor again, this time with the designation of Tong Fengge Luantai Pingzhangshi. However, he was soon falsely accused of unspecified crimes—and Empress Dowager Wu gave the case to Qian's subordinate Zhou Ju (周矩) for investigation. It was said that Qian had often been unimpressed with Zhou and rebuked him for being unable to complete tasks. When Zhou interrogated Qian, Zhou stated, "You often rebuke me for being unable to complete tasks. I will complete one for you today." Around the new year 689, Qian and his son Qian Ciyu (騫辭玉) were executed.

騫味道（？ - 689年），唐朝金城（今甘肅蘭州）人，在唐睿宗第一次在位、武則天臨朝期間，684年—685年（同鳳閣鸞臺三品）、688年—689年（同鳳閣鸞臺平章事）擔任宰相。

騫味道任宰相之前的經歷幾乎沒有記載，《舊唐書》和《新唐書》一般有宰相的傳，卻都沒有他的傳。684年九月，騫味道時任左肅政大夫（左御史大夫），當時英國公李敬業反對睿宗的母親武則天臨朝稱制在揚州造反，宰相裴炎說太后將權力交給皇帝，叛亂自然平定。李景諶証明裴炎必定謀反。騫味道和魚承曄主持審理裴炎，武則天以裴炎勾結李敬業謀反之罪，將他處死。騫味道被太后武則天任命為檢校內史、同鳳閣鸞臺三品，成為宰相。685年正月初四，唐朝任命騫味道守內史。司門員外郎房先敏被貶衛州司馬，他向宰相申訴。騫味道對他說：「這是皇太后的決定。」內史侍郎同三品劉禕之說：「你因獲罪改任官職，是有關官員奏請的結果。」武后得知，認為騫味道有功歸己，有過推君，四月初一，貶他為青州刺史。688年之前，騫味道被重新任命為左肅政大夫，九月十二，騫味道和夏官侍郎王本立再任同鳳閣鸞臺平章事。騫味道看不起殿中侍御史周矩，認為他不能解決問題。後來騫味道被告發，武則天命周矩審訊他。周矩對他說：「你老說我不能解決問題，今天我就解決你的問題。」689年1月11日，確定罪行，騫味道與其子騫辭玉都被處死。
