Whenever he's at the crease, the whole of India (over 1bn people) grinds to a halt to watch him weave his batting magic.
Here are 10 reasons why the man is a walking legend.
New balls please! Sachin originally wanted to be a professional tennis player. When he started playing cricket he wanted to be a fast bowler, but because of his height (or lack of it), he became a batsman.
Sachin was given a pair of pads by his cricket hero Sunil Gavaskar when he was a schoolboy - and he made his Test debut for India against Pakistan aged just 15-years old in 1989 wearing those very pads.
The Little Master...when he was a little master
The first of many - Sachin was just 17 years and 109 days old when he scored his debut Test century against England at Old Trafford back in 1990, finishing up on 119 not out.
Sachin was the first ever foreign cricketer to play for Yorkshire in 1992. Before then, only players who were born in the county were ever allowed to play for Yorkshire. But the rules were changed and in came a 19-year-old Sachin, scoring 1000 runs at an average of 46.
Unenviable record - Sachin was the first batsman ever to be given out by the third umpire when he was run out against South Africa in the first Test in Durban back in 1992.
He uses an incredibly heavy bat at the crease, weighing in at 3.2lbs - in fact, only South Africa's master blaster Lance Klusener uses a heavier bat in world cricket.
Like loads of other cricketers, Sachin is pretty superstitious - he'll always put on his left pad before his right whenever he's getting padded up.
Ah no! Sachin's rolled into town!
Off the pitch, Sachin seriously loves his motorsport. In 2002 he was given a brand-spanking new Ferrari 360 Modena by six-time World Champion Michael Schumacher at Silverstone!
Take one! Sachin made a special appearance in the Bollywood film "Stumped" in 2003 as himself.
Shane Warne once said: "I'll be going to bed having nightmares of Sachin just running down the wicket and belting me back over the head for six".
