Yes, you can - if you are not using strict refs:

for my $element (qw/var1 var2 var3/) { %$element = ( a => 'b'); } print $var1{a};
The common practice, though, is to use one hash instead, making the elements of the list the keys. You can then shorten the creation to
my @array = qw(var1 var2 var3); my %hash; undef @hash{@array};
