Arnoldus 'Andy' Mauritius Blignaut (born 1 August 1978, Salisbury (now Harare)) is a Zimbabwean cricketer. He is a formidable right-arm medium-fast bowler, but he is also known for his vicious form with the bat in ODI's, where his frequent scoring of runs at an exceptionally fast rate is a valuable asset, though seeing him sustaining this form and keeping his wicket intact through many overs is a rare event. Due to this, he more often plays ODI's, where many runs in a short time are desired, than he plays tests.

His ODI strike rate is over 100 (as of December 2004), with a high score of 63 not out, and an unfortunate average of just 19, betraying his aggressive (but dangerous) style. His bowling average is just above 43, with best bowling figures of 4/43, and an economy of 5.18. He is also a fine fielder.

He hails from an Afrikaner farming family, and is by all accounts an easy-going, friendly man.
