The Blues' seconds led Hampshire division one by one point from Overton when the sport was suspended because of the coronavirus pandemic.
It may not quite be the way Chi wanted to win the league - but champions they are and they can now look forward to starting next season in the Hampshire premier, where they will play two derbies against Bognor.
A Chi RFC statement said: "Following the early end of the rugby season in England, as a result of Covid-19, the RFU has announced the final league positions. Chichester 2nd XV have been confirmed as champions of Hampshire 1 and are promoted to Hampshire Premier.
"It was a very competitive season that saw Chichester finish one point ahead of Overton, with Southampton University Hospitals and Locks Heath Pumas both four points further back.
Top of the league changed six times after Christmas and Chichester regained top spot with their win away at Fawley on March 14. Next season we look forward to a local derby with Bognor!"
The early end to the season and the decision to award final placings on results in the bank does not affect Chichester's first XV nor Bognor, who play in London one south and the Hampshire premier respectively. Neither was set for promotion or relegation.
A message from the Editor, Gary Shipton:
Thank you for reading this story on our website.
But I also have an urgent plea to make of you.
In order for us to continue to provide high quality local news on this free-to-read site and in print, please purchase a copy of our newspaper as well. With the coronavirus lockdown having a major impact on our town centres and many of our valued advertisers - and consequently the advertising that we receive - we are more reliant than ever on you buying a copy.
Our journalists are highly trained by the National Council for the Training of Journalists (NCTJ) and our content is independently regulated by IPSO to some of the most rigorous standards anywhere in the world. Our content is universally trusted - as all independent research proves.
As Baroness Barran said in a House of Lords debate this week on the importance of journalists: "Not only are they a trusted source of facts, but they will have a role to play in rallying communities and getting the message across about how we can keep ourselves and our families safe, and protect our NHS. Undoubtedly, they have a critical role."
But being your eyes and ears comes at a price. So we need your support more than ever to buy our newspapers during this crisis. In return we will continue to forensically cover the local news - not only the impact of the virus but all the positive and uplifting news happening in these dark days.
In addition, please write to your MP urging the Government to provide some additional financial support for local newspapers and their websites like this one and ensuring that supermarkets continue to stock them. I cannot stress enough how important such an intervention would be.
We thank all our readers and advertisers for their understanding and support - and we wish YOU all the best in the coming weeks. Keep safe, and follow the Government advice. Thank you.
