grep -E -e 'Mickey' -e 'Minnie' -e 'Pluto' < myfile

Man grep for details (of course, if you had done that you wouldn't have needed to ask).

You can use the -e option on grep.

grep -e this -e that filename

This would return lines containing either "this" or "that".

VOM,

According to man pages:

"-e expression Same as a simple expression argument, but useful when the expression begins with a hyphen (-). Multiple -e options can be used to specify multiple patterns; an input line is selected if it matches any of the specified patterns."

Regards,

Jaime

I should add that the grep -E (enhanced) may well be a better choice because unlike plain grep (without the -E) you can do much more powerful Regular Expression matches rather than simple strings.
