In this work by the index of fixed point and matrix theory, we discuss the positive solutions for the system of Riemann–Liouville type fractional boundary value problemsD  0 +  α  u  ( t )  +  f 1   ( t , u  ( t )  , v  ( t )  , w  ( t )  )  = 0 , t ∈  ( 0 , 1 )  ,D  0 +  α  v  ( t )  +  f 2   ( t , u  ( t )  , v  ( t )  , w  ( t )  )  = 0 , t ∈  ( 0 , 1 )  ,D  0 +  α  w  ( t )  +  f 3   ( t , u  ( t )  , v  ( t )  , w  ( t )  )  = 0 , t ∈  ( 0 , 1 )  ,u  ( 0 )  =  u ′   ( 0 )  = ⋯ =  u  ( n − 2 )    ( 0 )  = 0 ,  D  0 +  p    u  ( t )  |   t = 1   =  ∫ 0 1  h  ( t )   D  0 +  q  u  ( t )  d t ,v  ( 0 )  =  v ′   ( 0 )  = ⋯ =  v  ( n − 2 )    ( 0 )  = 0 ,  D  0 +  p    v  ( t )  |   t = 1   =  ∫ 0 1  h  ( t )   D  0 +  q  v  ( t )  d t ,w  ( 0 )  =  w ′   ( 0 )  = ⋯ =  w  ( n − 2 )    ( 0 )  = 0 ,  D  0 +  p    w  ( t )  |   t = 1   =  ∫ 0 1  h  ( t )   D  0 +  q  w  ( t )  d t ,whereα ∈ ( n − 1 , n ]withn ∈ N    ,n ≥ 3    ,p , q ∈ Rwithp ∈ [ 1 , n − 2 ]    ,q ∈ [ 0 , p ]    ,D  0 +  αis the    α    order Riemann–Liouville type fractional derivative, andf i   ( i = 1 , 2 , 3 )  ∈ C  (  [ 0 , 1 ]  ×  R +  ×  R +  ×  R +  , R )are semipositone nonlinearities.
