Alexander Watt Williamson (1849 – 2 August 1928) was a New Zealand schoolteacher. In 1874 he became the first person to receive a degree from a New Zealand university. He received the first and only degree issued by the University of Otago before it merged into the University of New Zealand (which in 1961 was dissolved into four independent universities and two associated agricultural colleges). Later, in 1876, Williamson was reissued a Bachelor of Arts degree certificate from the University of New Zealand.
