Answering your question can be a bit tricky. Similar to many US shows, production for the 14th season of Blue Bloods came to a halt due to the ongoing strikes involving both writers and actors that began earlier this year.
Rest assured, the 14th season is confirmed to be in the works. A recent report from The Hollywood Reporter revealed that the show’s stars and producers made concessions by accepting pay cuts to ensure the series’ continuation. However, as of now, filming has not yet commenced.
If filming manages to kick off before the year’s end in 2023, the earliest we can expect to see new episodes would likely be in the spring of 2024.
