The modern musical romance has swept film fans off their feet, and its stars Emma Stone and Ryan Gosling are expected to be among the nominees.
The question is - how many nominations will the film get in total, and can it equal the Oscars record of 14?
Titanic and All About Eve currently share that record, while Mary Poppins is the most nominated musical with 13.
This year's other contenders will include Moonlight, about a young black man dealing with his sexuality in drug-torn Miami; brooding domestic drama Manchester by the Sea; and cerebral sci-fi film Arrival.
In the acting categories, Jackie's Natalie Portman is likely to challenge Emma Stone for best actress, while Manchester by the Sea's Casey Affleck and Fences' Denzel Washington are tipped to give Gosling competition for best actor.
Almost certainly not. After two years with no non-white acting nominees, this year we could see four or five - possibly Washington (who also directed Fences), Viola Davis (Fences), Naomie Harris (Moonlight), Mahershala Ali (Moonlight) and Octavia Spencer (Hidden Figures).
Naomie Harris is flying the flag for British actresses, while male candidates could include Andrew Garfield (Hacksaw Ridge), Aaron Taylor-Johnson (Nocturnal Animals), Dev Patel (Lion) - and Hugh Grant (Florence Foster Jenkins), who could get his first nomination. But there probably won't be much for Ken Loach's benefits drama I, Daniel Blake.
Meryl Streep will become the first person to notch up 20 acting nominations if she gets in for Florence Foster Jenkins. She was an outsider - but her odds have shortened since berating Donald Trump at the Golden Globes.
If it is, it will be the first superhero movie to be nominated for the top award. It has a chance - it was nominated for the Golden Globes and Producers Guild of America Awards, among others, and its star Ryan Reynolds posted a brilliant video to launch its campaign.
Arrival, in which Amy Adams tries to talk to aliens, could well be second to La La Land when the nominations are totted up, partly thanks to its chances in the technical categories - despite Manchester by the Sea and Moonlight being talked about alongside La La Land as this year's main contenders.
After a series of racist and sexist rants over the past two decades, Mel Gibson's comeback movie Hacksaw Ridge will get nominations. But will Academy members bring themselves to nominate him for best director?
Despite his reputation as an Oscar favourite, Tom Hanks hasn't had a nomination since 2001. His latest role as Hudson River pilot Chesley Sullenberger in Sully surely ticks the Academy's boxes.
The Academy Award nominations are announced from 13:18 GMT on Tuesday, with the winners to be named in Los Angeles on 26 February.

The plans include the rebuilding of the North/South Stand and an increase in ground capacity from 17,000 to 20,000.
Club chairman Colin Graves said the changes were necessary to ensure the ground could continue to host international matches.
A detailed consultation over the plans will be held, the club said.
If given the go-ahead, the proposals will also see the installation of floodlights, extra seating in the upper tier of the North East Stand and the development of a new five-storey pavilion.
The phased "transformation" of the Headingley ground will take about 20 years to complete, the club said.
Mr Graves said it was "the most ambitious project the club and the venue will have undertaken since the ground was first established 125 years ago".
"As other venues around the country continue to invest in their facilities, we cannot afford to stand still and expect that Headingley will always host international cricket," he said.
"The stark reality is that if our stadium fails to evolve, we will lose our Test Match status which would be a devastating blow to the region."
The club will work with Leeds Rugby - which is also based at the Headingley ground - and Leeds City Council to prepare for the redevelopment work, the club said.
This year's Oscar nominations are due out later, with La La Land likely to land as the clear frontrunner.
