Do Mormons believe Jesus Christ was a polygamist?
Questions and Answers
Question: Do Mormons believe Jesus Christ was a polygamist?
There is no official doctrine regarding Jesus' marital state
The Bible is silent on the issue of Jesus' (or the Father's) marital state, and there has been no modern revelation stating he was or was not married. This leaves the issue an open question. Jesus' purported polygamy plays little if any role in present-day LDS discourse.
Therefore, the easy answer is that no, Latter-day Saint doctrine does not teach that Jesus was married, polygamist or otherwise. In fact, there is no official Church doctrine on this issue. Members are free to believe as they wish concerning this matter.

Charles W. Penrose:
Question 2: Do you believe that Jesus was married?
Answer: We do not know anything about Jesus Christ being married. The Church has no authoritative declaration on the subject. 
Question: Did early Mormon leaders believe that Jesus Christ was a polygamist?
A few Church leaders believed this, but the idea was never official Church doctrine
Since members in the nineteenth century were commanded to practice polygamy, many presumed that Jesus would have had to also practice this law.
Jedediah M. Grant
Jedediah M. Grant said:
This ancient philosopher says they were both John's wives. Paul says, "Mine answer to them that do examine me is this:—.Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas." He, according to Celsus, had a numerous train of wives.
The grand reason of the burst of public sentiment in anathemas upon Christ and his disciples, causing his crucifixion, was evidently based upon polygamy, according to the testimony of the philosophers who rose in that age. A belief in the doctrine of a plurality of wives caused the persecution of Jesus and his followers. We might almost think they were "Mormons."
But if you pass on in their history to seek for uniformity and beauty, you will find some grand flare-ups among them. Look, for instance, at Paul and Peter, disputing and quarrelling with each other....
Grant believed that early writers, hostile to the Christians, charged members and even Jesus, with polygamy (a charge which would have offended sophisticated Roman opinion in the day). Grant sees the obvious parallels with how the Saints have been treated over the same issue, but Jesus' marital state is not his main point, but conflict and persecution. (It is not clear, however, to which source Grant is referring—FAIR has been unable to locate any such reference to Celsus.)
Likewise, Orson Hyde remarked:
I discover that some of the Eastern papers represent me as a great blasphemer, because I said, in my lecture on Marriage, at our last Conference, that Jesus Christ was married at Cana of Galilee, that Mary, Martha, and others were his wives, and that he begat children.
All that I have to say in reply to that charge is this—they worship a Savior that is too pure and holy to fulfil the commands of his Father. I worship one that is just pure and holy enough "to fulfil all righteousness;" not only the righteous law of baptism, but the still more righteous and important law "to multiply and replenish the earth." Startle not at this! for even the Father himself honored that law by coming down to Mary, without a natural body, and begetting a son; and if Jesus begat children, he only "did that which he had seen his Father do."
Hyde is again not focused on Jesus' matrimonial state, and notes that being married and begetting children—polygamously or otherwise—is no evil, but is in accordance with God's commandments from time to time.
