The Wales and Real Madrid star will receive a slice of £2.35million towards the project.
It will go on converting an empty building into a 23,000sq ft golf bar in his home city of Cardiff.
Called Par 59, it will open in spring and have three nine-hole courses, a bar and a restaurant.
Bale, 32, who is paid about £500,000 a week, already owns the Elevens sports bar nearby.
His newest venture is one of three businesses to get an undisclosed share of an interest-free Welsh government loan.
Cardiff council said the bar would help the city’s post-pandemic recovery.
Par 59 co-founder Nick Saunders said it would create 45 jobs and occupy a site that had been empty for six years.
