The Bill will mean all adults automatically become organ donors, unless they choose not to be
It's hoped the opt-out organ donation system will allow quicker access to those on waiting lists.
The Human Tissue Bill is expected to pass through the Oireachtas today, meaning all adults automatically become organ donors unless they choose not to be.
There are currently 601 people waiting for a transplant, with that number expected to rise over the coming years.
Once passed, it will be sent to President Higgins to be signed into law.
