it's all in sys.tables, but i prefer to use built in functions instead of joining sys.schemas:

SELECT

SCHEMA_NAME(schema_id) As SchemaName ,

name As TableName

from sys.tables

ORDER BY name

--alternate:

SELECT

sch.name As SchemaName ,

tbl.name As TableName

from sys.tables tbl

inner join sys.schemas sch on tbl.schema_id = sch.schema_id

ORDER BY tbl.name

I typically just go for sys.objects like the following.

SELECT SCHEMA_NAME(schema_id) As SchemaName

,name As TableName

FROM sys.objects

WHERE type = 'U'

An interesting sidebar on this is that if you look at the execution plan, the version going to sys.tables will get it's data from sysschobjs and sysidxstats and will cost a little bit more than just going direct to sys.objects (for which sysschobjs is the base object).

You can also use the following:

SELECT Table_Schema, Table_Name

FROM information_schema.tables

WHERE table_type = 'BASE TABLE'
