  We present nine bijections between classes of Dyck paths and classes of
standard Young tableaux (SYT). In particular, we consider SYT of flag and
rectangular shapes, we give Dyck path descriptions for certain SYT of height at
most 3, and we introduce a special class of labeled Dyck paths of semilength
$n$ that is shown to be in bijection with the set of all SYT with $n$ boxes. In
addition, we present bijections from certain classes of Motzkin paths to SYT.
As a natural framework for some of our bijections, we introduce a class of set
partitions which in some sense is dual to the known class of noncrossing
partitions.
