The present invention provides an olefin polymerization catalyst by the use of which an olefin (co)polymer can be obtained with a high polymerization activity, and also provides a process for olefin polymerization using the catalyst. The olefin polymerization catalyst comprises a transition metal compound (A) represented by the formula (I):
M: atom of Group 3 to Group 11
U: R2-C, N, P
A: N, P
Q: R3-C, N, P
S: R4-C, N, P
T: R5-C, N, P
m: 2 - 6
R1 - R5: hydrogen, hydrocarbon group, silicon-containing group or the like (When M is an atom of Group 6, R1 is not an aromatic hydrocarbon group.)
n: number satisfying a valence of M
X: halogen, hydrocarbon group or the like
