Millwall winger Taylor, 26, and Notts County midfielder Judge, 24, both arrive on free transfers after passing medicals with Rovers and will officially sign on July 1st.
The two deals are something of a coup for Rovers, as both players were being chased by Premier League and Championship clubs.
Taylor joins Rovers having spent just one year with Millwall following his move from Oldham Athletic but he impressed at The Den during his stint and has now sealed a deal with Blackburn.
For Judge, he actually returns to the club where he began his career, and he made two cup appearances for the club before leaving for Notts County in 2011.
He has since emerged as one of the most capable midfielders outside the top-flight and Rovers have moved quickly to bring him back to Ewood Park.
